[0047] Embodiment 2:

[0048] The present invention also discloses a method for replacing bolts of a coke oven concrete sleeper pressure plate. Based on the replacement tool in the first embodiment, the replacement method comprises the following steps:

[0049] Step S1, the replacement tooling is set on the rail, and the walking roller is movable along the rail; specifically, the replacement tooling is hoisted onto the rail by a lifting device, and according to the working environment conditions and actual needs, the driving device can be operated by an electrical control system or manually driven to achieve the purpose of the replacement tooling walking. The driving device is mainly composed of a 2.2KW single-stage split cycloid reducer, a motor (power 2.2KW with a detachable manual driving device-B-shaped handle), and a 16A transmission chain (matching sprocket). When there is energy control (electricity), the walking is controlled by electricity, and when there is no electricity, manual drive can be selected to control the walking.

[0050] Step S2, moving the sliding platform plate so that the drilling rig operation hole is aligned with the part of the pressure plate bolts to be replaced, and using the gripping device to grip the rail to fix the position of the platform plate.

[0051] Specifically, when the tooling is replaced and walked to the working section (i.e. the drilling rig operating hole is aligned with the pressure plate bolts to be replaced), the hydraulic device is started, and the telescopic (raising and lowering) function of the cylinder is used to clamp or grab the rails to ensure that the platform plate can be effectively fixed on the rails, thereby achieving the stability of the water drill mechanism during operation, thereby solving the problem of using a clamp to stabilize the water drill.

[0052] Step S4, using a water drill mechanism to remove the bolts of the pressure plate to be replaced that are aligned with the drilling rig operation hole.

[0053] Specifically, the water drill mechanism is aligned. In this operation section, when the platform plate is not moved, multiple sets of pressure block bolts can be replaced in pairs. Since the base of the water drill body is composed of a pedestal and a straight slide, the purpose of rotating the straight slide is to adjust the centering offset between the drill bit and the pressure plate bolts without moving the platform plate, thereby adjusting the centering offset by moving the water drill back and forth.

[0054] Step S5, release the gripping device and move the platform plate to continue removing the next part of the pressure plate bolts to be replaced.

[0055] Step S6, after all the pressure plate bolts to be replaced are removed, new bolts are installed in situ, and concrete is poured to fix the new bolts.
