Technical Field
[0001] This utility model relates to the field of rail clamping technology, and in particular to a rail clamping device. Background Technology
[0002] Rail clamps are an important safety device used to ensure the stability of machinery during operation and prevent slippage when subjected to unexpected forces. In factories, rail clamps are typically used to fix equipment to rails, preventing misalignment and vibration during operation, which could disrupt normal production and cause equipment damage.
[0003] However, existing technologies, such as Chinese patent application CN218191015U, disclose a rail clamp for track-walking equipment, including a track and a support plate. A vertical plate is welded to one side of the support plate, and suspension springs are attached to both sides of the vertical plate. A rotating plate is attached to the other end of each suspension spring. A clamp is welded to one side of the rotating plate, and a through hole is provided in the middle of the clamp. A stud shaft is inserted into the through hole, and fixing nuts are threaded onto both sides of the stud shaft. The rotating plate has internal threaded holes, and fastening bolts are threaded into these internal threaded holes. This design is simple in structure, easy to maintain, and the parts are easy to replace, preventing rail jamming.
[0004] The above technical solution uses a connection structure between iron plates, bolts, and suspension springs to achieve a simple structure, convenient maintenance, easy replacement of parts, and avoidance of rail jamming. However, in actual use, while the above solution has a simple structure, it requires more manual intervention, has a low degree of automation, and lacks structures to improve the stability of the rails. Utility Model Content
[0005] The purpose of this invention is to solve the problems in the existing technology, such as low automation and lack of structures to improve the stability of the track.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rail clamp, comprising a rail and an outer frame, wherein a motor is provided on the left outer side of the outer frame, a lead screw is fixedly embedded at the center of the motor, the lead screw passes through the interior of the outer frame, and the other end of the lead screw is connected to the right inner side of the outer frame through a bearing, two opposing square blocks are movably sleeved on the lead screw, a slider is fixedly installed at the upper end of each of the two square blocks, a square post is fixedly installed at the lower end of each of the two square blocks, a connecting post is movably embedded at the lower end of the square post, and a clamp is fixedly installed at the lower end of the connecting post.
[0007] In a preferred embodiment, the bottom of the left and right sides of the outer frame has symmetrical square openings, and two guard plates are fixedly installed on the two sides. A fixed shaft is fixedly embedded between the two guard plates, and a roller is movably sleeved on the fixed shaft. Limiting circular plates are fixedly installed at the center of both ends of the roller.
[0008] The technical effect of adopting the above-mentioned further solution is that, through the above structural connection, a pair of simple rollers can be formed in the outer frame along the track direction, so that the rail presser can be pushed manually to move along the track to the work area, avoiding manual handling and increasing the workload.
[0009] In a preferred embodiment, a sliding groove is provided at the center line of the top surface of the outer frame, and the front and rear sides and the bottom surface of the outer frame are all open.
[0010] The technical effect of adopting the above-mentioned further solution is that it facilitates the adjustment of the left-right distance between the two sets of clamps, adjusts the appropriate clamping position, and thus improves the stability of the rail.
[0011] In a preferred embodiment, the lead screw has threaded sections with opposite directions of rotation at both ends, and the two square blocks are each fitted onto the threaded sections at both ends of the lead screw.
[0012] The technical effect of adopting the above-mentioned further solution is as follows: when the motor is turned on, the lead screw rotates. Since the two ends of the lead screw are provided with threaded sections with opposite directions of rotation, it will drive the two square blocks to move towards each other. The movement is transmitted through the square column and the connecting column and drives the two sets of opposite clamps to move towards each other, thereby achieving the squeezing and pressing of the rail.
[0013] In a preferred embodiment, the square column has a rectangular groove at its bottom and U-shaped through holes on its front and rear sides. The square column and the connecting column are connected by screws, nuts and washers.
[0014] The technical effect of adopting the above-mentioned further solution is that it enables the relative position of the two sets of clamps to be freely adjusted, while the connecting post and the square post are firmly secured by connecting them with screws, nuts and washers.
[0015] In a preferred embodiment, the connection between the connecting post and the clamp is achieved by welding.
[0016] The technical effect of adopting the above-mentioned further solution is that it can improve the stability between the connecting column and the clamp, and ensure that the two will not undergo slight misalignment under pressure, thus preventing problems such as work accidents.
[0017] In one preferred embodiment, the connecting column and clamp are in two sets, with two clamps in each set, and are installed symmetrically to the centerline of the track.
[0018] The technical effect of adopting the above-mentioned further solution is that setting multiple sets can improve the stability of the rail clamp during operation.
[0019] In a preferred embodiment, the two square blocks are fixedly installed in the middle of the square column, and threaded through holes are opened at the geometric center of the opposite sides.
[0020] The technical effect of adopting the above-mentioned further solution is that by setting threaded through holes on the square block, the rotation of the lead screw drives the square block to move, thereby driving the square column to move.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] 1. In operation, the outer frame of the rail clamp is equipped with a lead screw, with threaded sections at both ends of the lead screw having opposite directions of rotation.

The upper ends of the two square blocks are fixedly connected to the lower ends of the sliders, and the upper ends of the sliders are movably embedded in the grooves on the top surface of the outer frame. The lower ends of the two square blocks are fixedly connected to square columns, and the lower ends of the square columns are embedded in the upper ends of the connecting columns. The two are fixed by screws, nuts, and washers. The lower ends of the connecting columns are fixedly connected to clamps. When the motor is turned on, the lead screw rotates. Because the two ends of the lead screw have threaded sections with opposite directions of rotation, it will drive the two square blocks to move towards each other. The movement is transmitted through the square columns and connecting columns and drives the two sets of opposing clamps to move towards each other, while moving closer to both sides of the rail, thereby achieving the squeezing and pressing of the rail. The operation is simple and highly automated.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figure 1-6 This utility model provides a technical solution: a rail clamp, including a rail 1 and an outer frame 2. A motor 3 is provided on the left outer side of the outer frame 2. A lead screw 4 is fixedly embedded in the center of the motor 3. The lead screw 4 passes through the interior of the outer frame 2. The other end of the lead screw 4 is connected to the right inner side of the outer frame 2 through a bearing. Two opposing square blocks 5 are movably sleeved on the lead screw 4. A slider 51 is fixedly installed on the upper end of each of the two square blocks 5. A square post 6 is fixedly installed on the lower end of each of the two square blocks 5. A connecting post 7 is movably embedded in the lower end of the square post 6. A clamp 8 is fixedly installed on the lower end of the connecting post 7.
[0034] like Figure 1-6 As shown, square openings are symmetrically opened on the bottom of the left and right sides of the outer frame 2. Two guard plates 21 are fixedly installed on both sides. A fixed shaft 24 is fixedly embedded in the middle of the two guard plates 21. A roller 22 is movably sleeved on the fixed shaft 24. Limiting circular plates 23 are fixedly installed at the center of both ends of the roller 22. Through the above structural connection, a pair of simple rollers can be formed on the outer frame 2 along the direction of the track 1, so that the rail presser can be pushed manually to move along the track 1 to the working area, avoiding manual handling and increasing the workload.
[0035] like Figure 1-6 As shown, a sliding groove is provided at the center line of the inner top surface of the outer frame 2. The front and rear sides and the bottom surface of the outer frame 2 are open, which facilitates the adjustment of the left and right distance between the two sets of clamps 8, and adjusts the appropriate clamping position to improve the stability of the track 1.
[0036] like Figure 1-6As shown, the lead screw 4 has threaded sections with opposite directions of rotation at both ends. Two square blocks 5 are respectively fitted onto the threaded sections at both ends of the lead screw 4. When the motor 3 is turned on, the lead screw 4 rotates. Since the lead screw 4 has threaded sections with opposite directions of rotation at both ends, it will drive the two square blocks 5 to move towards each other. The movement is transmitted through the square column 6 and the connecting column 7, and drives the two sets of opposite clamps 8 to move towards each other, thereby squeezing and pressing the rail 1.
[0037] like Figure 1-6 As shown, the square column 6 has a rectangular groove at the bottom and U-shaped through holes on the front and rear sides. The square column 6 and the connecting column 7 are connected by screws 61, nuts 62 and washers 63, which allows the left and right distances of the two sets of clamps 8 to be freely adjusted. At the same time, the connecting column 7 and the square column 6 are secured by the connection of screws 61, nuts 62 and washers 63.
[0038] like Figure 1-6 As shown, the connection between the connecting column 7 and the clamp 8 is welded, which can improve the stability between the connecting column 7 and the clamp 8 and ensure that the two will not undergo slight misalignment when under pressure, thus preventing work accidents and other problems.
[0039] like Figure 1-6 As shown, there are two sets of connecting columns 7 and clamps 8, with two clamps in each set and they are installed symmetrically to the centerline of the rail 1. Setting multiple sets can improve the stability of the rail clamp during operation.
[0040] like Figure 1-6 As shown, two square blocks 5 are fixedly installed in the middle of the square column 6, and threaded through holes are opened at the geometric center of the opposite side. By setting threaded through holes on the square blocks 5, the screw 4 can rotate to drive the square blocks 5 to move, thereby driving the square column 6 to move.
[0041] Working principle: Before operation, the two sets of clamps 8 of the rail clamp are in a loose state. First, the entire rail clamp is placed on the rail 1. Rollers 22 are symmetrically installed on the front and rear sides of the rail clamp. The rollers 22 fit against the rail 1. Limiting round plates 23 are provided at both ends of the rollers 22 to prevent the rail clamp from swaying left and right. At this time, the rail clamp can be pushed manually to move the rail clamp along the rail 1 to the working area, avoiding manual handling and reducing the workload. During operation, the rail clamp's outer frame 2 is equipped with a lead screw 4. The two ends of the lead screw 4 are provided with threaded sections with opposite directions of rotation. Two square blocks 5 are oppositely fitted on the two threaded sections of the lead screw 4. The upper ends of the two square blocks 5 are fixedly connected to the lower ends of the slider 51. The upper ends of the slider 51 are movably embedded in the sliding groove on the inner top surface of the outer frame 2. The lower ends of the two square blocks 5 are fixedly connected to the square posts 6. The lower ends of the square posts 6 are embedded in the upper ends of the connecting posts 7. The two are fixed by screws 61, nuts 62 and washers 63. The lower end is fixedly connected to clamp 8. When motor 3 is turned on, lead screw 4 rotates. Since the two ends of lead screw 4 are provided with threaded sections with opposite directions of rotation, it will drive the two square blocks 5 to move towards each other. The movement is transmitted through square column 6 and connecting column 7 and drives the two sets of opposite clamps 8 to move towards each other, while approaching both sides of the rail 1, thereby squeezing and pressing the rail 1. The operation is simple and highly automated. On this basis, this device can also freely adjust the left and right distance of the two sets of clamps 8. Before work, according to the construction requirements, loosen nut 62 and washer 63 and remove screw 61. The lower end of square column 6 is provided with a rectangular groove. Connecting column 7 is movably embedded in the groove. Move connecting column 7 to a suitable position, install screw 61, nut 62 and washer 63 and tighten them. Then turn on motor 3, clamp 8 clamp and complete the work. By adjusting the left and right distance of the two sets of clamps 8, the appropriate clamping position can be adjusted, thereby improving the stability of rail 1.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
