Abstract

A device comprises a frame, a plurality of fingers, and an integrated slide hammer to drive a coupler onto a first pipe. The device may drive the coupler backwards onto a second pipe. The device may position the coupler for fusion without having to remove the device for the backward driving of the coupler. The device may be used above ground or in a trench.

Claims

1. A device for installing a coupler onto a pipe, the device comprising:

a main plate that is configured to engage and drive a portion of a first transverse surface of the coupler in a first direction;

a stop plate that is configured to engage and drive a portion of a second transverse surface of the coupler that is opposite the first transverse surface in a second direction that is substantially opposite the first direction;

a guide that is coupled to the main plate and the stop plate; and

a hammer that is slidably affixed to the guide and configured to slide between the main plate and the stop plate,

wherein the main plate comprises;

a body having an opening; and

a plurality of fingers comprising a pair of adjacent fingers that are configured to form an open section.

2. The device of claim 1, further comprising:

a handle portion.

3. The device of claim 2, wherein the handle portion is positioned at an angle with respect to a longitudinal axis of the guide.

4. The device of claim 3, wherein the angle is about 135°

.

5. The device of claim 2, wherein the main plate comprises the handle portion.

6. The device of claim 2, wherein the stop plate comprises the handle portion.

7. The device of claim 1, wherein the hammer comprises an off-center channel.

8. The device of claim 1, further comprising:

an impact member configured to dampen a noise that results from the impact of the hammer.

9. The device of claim 8, wherein the impact member comprises:

a leather pad;

or

a rubber pad.

10. A device for installing a coupler onto a pipe, the device comprising:

a main plate that is configured to engage and drive a portion of a transverse surface of the coupler toward the pipe;

a guide that is coupled to the main plate; and

a hammer that is slidably affixed to the guide and configured to apply a force to the main plate to drive the coupler onto the pipe.

11. The device of claim 10, wherein the main plate comprises a pipe guide portion having a plurality of fingers.

12. The device of claim 11, wherein the plurality of fingers comprise at least two fingers that are configured to form an open section.

13. The device of claim 11, wherein the pipe guide portion comprises a body that is configured to engage and drive the transverse surface of the coupler toward the pipe.

14. The device of claim 11, wherein at least one of the plurality of fingers is configured to rest on a portion of a surface of the coupler.

15. The device of claim 13, wherein the body comprises an opening having a diameter that is greater than a diameter of the pipe.

16. A method for installing a coupler onto a pipe, the method comprising:

mounting a device with an integrated hammer on the coupler;

sliding a hammer in the device along a guide in a direction toward the pipe; and

impacting the hammer against a plate to engage and drive the coupler onto the pipe.

17. The method of claim 16, further comprising:

sliding the hammer in the device along the guide in a direction substantially opposite said direction toward the pipe.

18. The method of claim 17, further comprising:

impacting the hammer against a second plate to engage and drive the coupler onto a second pipe.

19. The method of claim 16, further comprising:

applying an electric current to the coupler to fuse the coupler to the pipe.

20. The method of claim 18, further comprising:

applying an electric current to the coupler to fuse the coupler to the pipe and the second pipe.
