Description

Technical Field

[0001] The utility model relates to the technical field of bracket bolt removal tools, in particular to a contact rail insulating bracket stainless steel bolt breaker. Background Art

[0002] Both the existing subway lines and the lines under construction use contact rails, which are supported by insulating brackets to ensure insulation from the ground. The insulating brackets consist of three parts: a bracket body, a bracket, and a claw. Each part is connected by stainless steel bolts. As an important part of the contact rail system, it needs to be inspected every year. During the inspection, the torque of the connecting bolts of each part of the insulating bracket needs to be calibrated. During the torque calibration, the bolts may slip and the bolts cannot be tightened in place, affecting the normal operation of the equipment.

[0003] There are still the following defects when dealing with the problem of bracket bolt stripping:

[0004] 1. When the bolts of the insulating bracket are stripped, the insulating bracket needs to be removed to meet the maintenance and protection requirements of the on-site insulating bracket. Due to the structural limitations of the insulating bracket itself, the angle grinder cannot complete the removal of the bracket screws. The claws need to be removed and the lifting rails need to be lifted and the insulating bracket body and bracket need to be removed as a whole before replacement;

[0005] 2. In order to meet the needs of handling the problem of bracket bolt stripping, when the bolts cannot be removed and replaced, on-site personnel need to carry sufficient insulation bracket spare parts for on-site emergency replacement needs. There are problems such as the insulation bracket is heavy and cannot be moved in time, and carrying a large number of spare parts affects the construction efficiency;

[0006] 3. For the dismantled insulation bracket, the bolts between the insulation bracket body and the bracket are thread-stripped and cannot be disassembled, so the insulation bracket body and the bracket can only be scrapped and cannot be used any further, which increases the replacement cost and causes certain economic losses.

On the one hand, it reduces the time for maintenance personnel to dismantle and replace the insulating bracket body and the bracket as a whole. On the other hand, it can avoid carrying a large number of insulating bracket spare parts. Moreover, due to the large dead weight of the body, the personnel transportation time is greatly reduced, and the hidden danger of secondary faults caused by untimely replacement of the insulating bracket, intrusion of the faulty insulating bracket, and inability of the contact rail to be effectively supported, which affects the power supply and causes driving safety, and solves the problems in the prior art.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a contact rail insulating bracket stainless steel bolt breaker, comprising a breaker body, a first nut fixing card, a through hole and a second nut fixing card, through holes are opened on both sides of the breaker body, and the first nut fixing card and the second nut fixing card are respectively arranged inside the breaker body, and the first nut fixing card and the second nut fixing card are both fixedly arranged on the inner wall of the breaker body.

[0009] Preferably, the breaker body is made of high-hardness steel.

[0010] Preferably, the through hole has a diameter of 2 cm for inserting a torque wrench.

[0011] Preferably, support seats are provided at both the upper and lower ends of the breaker body, and the support seats and the breaker body are an integral structure.

[0012] Preferably, the breaker body is rectangular.

[0013] Preferably, the inner walls of the first nut fixing card and the second nut fixing card fit with the hexagonal nuts and disc washers on the insulating bracket bracket bolts.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model is a contact rail insulating bracket stainless steel bolt breaker, which improves the efficiency of replacing the insulating bracket threaded bolts and ensures the power supply stability of the contact rail insulating bracket. On the one hand, it reduces the time for maintenance personnel to dismantle and replace the insulating bracket body and the bracket as a whole. On the other hand, it can avoid carrying a large number of insulating bracket spare parts. In addition, due to the large weight of the body, the transportation time of personnel is greatly reduced, and the hidden danger of secondary faults such as untimely replacement of the insulating bracket, intrusion of the faulty insulating bracket, and inability to effectively support the contact rail, which affects the power supply and leads to driving safety, is effectively eliminated. It has certain social benefits.

[0016] 2. The utility model is a contact rail insulating bracket stainless steel bolt breaker. After actual installation and comparison, the contact rail insulating bracket stainless steel bolt breaker has greatly improved the overall cutting and removal efficiency compared with the original insulating bracket, and the device can be operated by a single person, which greatly saves manpower and repair time, saves costs, has certain economic benefits, and can be promoted for use.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to solve the problem that the clamping bolt of the insulating bracket cannot be removed and replaced after the thread is slipped in the prior art, please refer to Figure 1-3 , providing the following technical solutions:

[0023] In this embodiment, a contact rail insulating bracket stainless steel bolt breaker includes a breaker body 1, a first nut fixing clip 2, a through hole 3 and a second nut fixing clip 4. Through holes 3 are provided on both sides of the breaker body 1, and the first nut fixing clip 2 and the second nut fixing clip 4 are respectively arranged inside the breaker body 1, and the first nut fixing clip 2 and the second nut fixing clip 4 are both fixedly arranged on the inner wall of the breaker body 1.

[0024] Since the nut to be broken is made of stainless steel, in order to ensure the stability of the breaker body 1, the breaker body 1 is made of high-hardness steel. The breaker body 1 is rectangular. The breaker is small in size, and its size is made according to the size comparison of each connection of the contact rail insulating bracket, which can meet the breaking effect of the connecting bolts of different types of insulating brackets. The internal size of the breaker is adjusted by the size of the insulating bracket connecting nut, which greatly improves the inspection and repair efficiency of the insulating bracket.

[0025] The diameter of the through hole 3 is 2 cm, and is used to insert a torque wrench to apply a longitudinal tightening force to the nut to achieve the effect of breaking the nut, thereby shortening the removal time of the stripped bolt, reducing the time for tightening the nut, and greatly improving the removal efficiency.

[0026] A support seat 5 is disposed at the upper end and the lower end of the breaker body 1 , and the support seat 5 and the breaker body 1 are an integral structure.

[0027] The inner walls of the first nut fixing clamp 2 and the second nut fixing clamp 4 fit with the M12 hexagonal nuts and disc washers on the insulating bracket bracket bolts.

[0028] Working principle: When in use, place the nut to be broken into the breaker body 1, and make the inner walls of the first nut fixing card 2 and the second nut fixing card 4 fit the insulating bracket bracket bolt disc gasket and nut, then insert the torque wrench into the through hole 3 and apply longitudinal twisting force to the nut to break the nut, the nut can be easily removed from the screw, and then the screw can be pulled out to separate the two parts connected by bolts.
