DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 As shown:

[0028] A guide rail clamp includes a rail body 101.

[0029] In this embodiment: the existing device {publication (announcement) number}: CN213231224U discloses a new guide rail clamp, in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the above design can easily extract and lock the rails when in use, and can use engineering machinery to lift single or spliced ​​multiple rails, saving time and effort, but when fixing the railway rails, the stability is poor due to the clamping on both sides of the wheels, which can cause the clamp and the rail to fall off, increase additional costs and risks, and reduce the use effect of the device." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve.

[0030] More specifically:

[0031] like Figures 1-4 As shown:

[0032] In combination with the above content: the track body 101 is provided with a clamp seat 102, the clamp seat 102 is provided with two sets of buckle plates 104 for clamping the two sides of the track body 101, and a locking ear 103 is provided above the clamp seat 102;

[0033] The clamp seat 102 is provided with a squeeze fixing mechanism 2, which can drive the clamp seat 102 and the pinch plate 104 to squeeze and lock the rail body 101;

[0034] The extrusion fixing mechanism 2 includes a U-shaped plate 201 welded to the upper surface of the clamp seat 102, a screw rod 202 disposed in the clamp seat 102, and an extrusion plate 203 rotatably connected to the bottom end of the screw rod 202 via a bearing;

[0035] A movable column 205 is fixed to the top of the screw 202, and the locking ear 103 is fixed to the upper surface of the U-shaped plate 201;

[0036] The clamp seat 102 is threadedly connected to the screw rod 202 through a threaded hole. The lower surface of the clamp seat 102 is provided with a slide groove adapted to the extrusion plate 203. The outer surface of the extrusion plate 203 is in contact with the side wall of the slide groove of the clamp seat 102.

[0037] The lower surface of the extrusion plate 203 and the contact end of the gusset plate 104 are both provided with anti-slip teeth 204, which are used to increase the friction force on the track body 101;

[0038] The clamp seat 102 is equipped with an elastic locking mechanism 3 that can drive two sets of gusset plates 104 to quickly lock on both sides of the track body 101;

[0039] The elastic locking mechanism 3 includes rectangular openings on both sides of the clamp seat 102, fixed rods 301 symmetrically arranged at the rectangular openings, and a spring 302 sleeved on the outer surface of the fixed rods 301;

[0040] The gusset plate 104 slides on the fixing rod 301 through the through hole, and the two ends of the spring 1 302 are fixedly connected to the gusset plate 104 and the clamp seat 102 respectively;

[0041] Locking blocks 303 are slidably connected to both sides of the pinch plate 104. A second spring 305 is fixed between the locking block 303 and the pinch plate 104. A slot 304 is provided on the inner side wall of the clamp seat 102 near the locking block 303. The locking block 303 is stuck in the slot 304 to lock the pinch plate 104 in position.

[0042] Both sides of the pinch plate 104 are provided with movable grooves adapted to the locking block 303 , and the locking block 303 and the pinch plate 104 are slidably connected through the movable grooves.

[0043] In this embodiment, when the guide rail clamp is in use, the locking block 303 is first pressed to make the locking block 303 slide in the moving groove of the pinch plate 104, and the locking block 303 is completely moved into the pinch plate 104. At this time, the locking block 303 is disengaged from the slot 304 opened by the clamp seat 102, and then the two sets of pinch plates 104 are pressed in the direction away from each other. At this time, the pinch plates 104 slide on the fixing rod 301 and squeeze the spring 1 302, so that the distance between the two sets of pinch plates 104 is expanded, and then they are stuck in the track. The locking block 303 is aligned with the slot 304, and the spring 2 305 is then released to lock the locking block 303 into the slot 304.

[0044] Then, a wrench (not shown in the figure) is used to clamp the movable column 205 and rotate the movable column 205, thereby driving the screw rod 202 to rotate. The setting of the movable column 205 makes it easier to rotate the screw rod 202, thereby improving the use effect of the device. As the screw rod 202 is rotated, the extrusion plate 203 is driven to move downward, so that the extrusion plate 203 slides in the slide groove. The slide groove is set to limit the extrusion plate 203, so that the extrusion plate 203 is more stable during the movement; as the extrusion plate 203 continues to move downward, the track body 101 is moved The friction between the extrusion plate 203 and the gusset plate 104 is increased, and the friction between the extrusion plate 203 and the gusset plate 104 and the rail body 101 is increased, thereby improving the fixing effect of the rail body 101. The mechanical connection end of the lifting device is then connected to the lock ear 103, and the rail body 101 can be lifted.

[0045] Through this operation, the stability of the clamping and fixing of the track body 101 is improved, the clamp and the track body 101 are less likely to fall off, the collision accidents caused by the shaking of the track body 101 are reduced, and the number of repeated adjustments and re-lifting required due to the instability of the track body 101 is reduced. This can save time, improve the overall construction efficiency, and improve the use effect of the device.

[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
