Description

Technical Field

[0001] This utility model relates to the field of gantry crane technology, specifically to a safety braking rail clamping device for a gantry crane. Background Technology

[0002] Gantry cranes are common industrial lifting equipment, mainly used for loading, unloading, and stacking goods in outdoor freight yards and material yards. Their structure resembles a portal frame, and they are a variation of bridge cranes. Their metal structure is a portal frame, with two legs mounted under the main beam, allowing them to travel on ground rails. The main components of a gantry crane include the main beam, legs, winch, trolley traveling mechanism, and electrical components.

[0003] However, in the prior art, when moving a gantry crane, since both the gantry crane and the track are exposed, water can easily get on the track and the moving wheels of the gantry crane, making it easy to slip and derail when moving quickly and stopping. Utility Model Content

[0004] The purpose of this utility model is to provide a safety braking rail clamping device for gantry cranes, which has the advantage of clamping and braking the gantry crane to prevent it from slipping and derailing during movement, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety braking rail clamping device for a gantry crane, comprising an installation assembly, wherein the installation assembly is provided with a rail clamping assembly and a tilting assembly, the rail clamping assembly comprising two upright plates, two rotating rods, two rotating blocks, two mounting plates, four support plates, two round rods, two rollers, two abutments, and two bonding plates, both upright plates being disposed on the installation assembly, the two rotating rods being rotatably mounted on the two upright plates respectively, the two rotating blocks being fixedly sleeved on the two rotating rods respectively, the two mounting plates being fixedly mounted on the outer walls of the two rotating blocks respectively, the four support plates being fixedly mounted on the outer walls of the two mounting plates respectively, the two round rods being rotatably mounted on the four support plates respectively, the two rollers being fixedly sleeved on the two round rods respectively, the two abutments being fixedly mounted on the two rollers respectively, and the two bonding plates being fixedly mounted on the two abutments respectively.

[0006] Furthermore, the two abutments are arranged opposite each other, and both abutments are arranged in a bent shape.

[0007] Furthermore, both of the aforementioned bonding plates are made of rubber.

[0008] Furthermore, a rectangular groove is provided on one outer wall of the mounting plate, and the rectangular groove is adapted to the abutment block.

[0009] Furthermore, the mounting assembly includes a base, a track, and a fixing plate. The track is fixedly mounted on top of the base, the fixing plate is positioned above the track, the fixing plate is welded to an external crane, and the upright plate is fixedly mounted on top of the fixing plate.

[0010] Furthermore, the flipping assembly includes a motor, two horizontal plates, two drive rods, two gears (first and second), a mounting bracket, and two anti-collision plates. The motor is fixedly mounted on the top of the fixed plate. The two horizontal plates are respectively fixedly mounted between the two vertical plates. The two drive rods are respectively rotatably mounted on the two horizontal plates. The two gears (first) are respectively fixedly mounted on the ends of the two drive rods that are far apart from each other. The two gears (second) are respectively fixedly sleeved on the two rotating rods. The gears (first and second) mesh with each other. The mounting bracket is fixedly mounted on the top of the two vertical plates. The two anti-collision plates are both fixedly mounted on the mounting bracket.

[0011] Furthermore, a soft rubber plate is fixedly installed on one side of the outer wall of the anti-collision plate.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention, by setting up a rail clamping assembly, allows the rollers to be driven and clamped onto the rail. As the gantry crane moves, the rollers roll, causing the round rod to rotate on the rail. The round rod rotates on the support plate, and the rollers drive the abutment block to rotate. The abutment block rotates and moves closer to the rail to fit against it. The abutment block drives the fitting plate to move and fit against the rail. At this time, the abutment block and the roller clamp the rail, initially braking the gantry crane. Furthermore, the fit between the abutment block and the rail applies a counterforce in the opposite direction of the gantry crane's movement, further braking it. This invention has the advantage of clamping and braking the gantry crane, preventing slippage and derailment during movement.

[0014] This invention features a flipping assembly. When the motor is started, it drives the drive rod to rotate. The drive rod rotates on the horizontal plate, which in turn drives gear one to rotate. Gear one meshes with gear two during rotation, causing gear two to rotate. Gear two then drives a rotating rod to rotate, which in turn drives a rotating block to rotate. The rotating block moves the mounting plate, which in turn moves the rollers and clamps the track. This design offers the advantages of flipping movement and clamping and braking the gantry crane. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides, for example Figures 1-4As shown, a safety braking rail clamping device for a gantry crane includes an installation assembly 1. The installation assembly 1 is equipped with a rail clamping assembly 2 and a tilting assembly 3. The rail clamping assembly 2 includes two upright plates 201, two rotating rods 202, two rotating blocks 203, two mounting plates 204, four support plates 205, two round rods 206, two rollers 207, two abutments 208, and two contact plates 209. The two upright plates 201 are both mounted on the installation assembly 1. The two rotating rods 202 are rotatably mounted on the two upright plates 201. The two rotating blocks 203 are fixedly sleeved on the two rotating rods 202. The two mounting plates 204 are fixedly mounted on the outer walls of the two rotating blocks 203. The four support plates 205 are fixedly mounted on the outer walls of the two mounting plates 204. The two round rods 206 are rotatably mounted on the four support plates 205. The two rollers 207 are fixedly sleeved on the two round rods 206. The abutment blocks 208 are respectively fixedly installed on the two rollers 207, and the two bonding plates 209 are respectively fixedly installed on the two abutment blocks 208. More specifically, when the rollers 207 are driven and clamp the track 102, the movement of the gantry crane causes the rollers 207 to roll. The rollers 207 roll on the track 102, causing the round rod 206 to rotate. The round rod 206 rotates on the support plate 205, and the rollers 207 cause the abutment blocks 208 to rotate. Block 208 rotates and moves closer to the track 102 to fit together. Block 208 drives the fitting plate 209 to move and fit together with the track 102. At this time, block 208 and roller 207 clamp the track 102, which initially brakes the gantry crane. By fitting block 208 with the track 102, an opposing force is applied to the direction of movement of the gantry crane, which further brakes it. This has the advantage of clamping the gantry crane to brake it and preventing the gantry crane from slipping and derailing when moving.

[0022] In addition, the two abutment blocks 208 are arranged opposite each other, and both abutment blocks 208 are arranged in a bent shape.

[0023] In addition, both of the aforementioned bonding plates 209 are made of rubber.

[0024] In addition, a rectangular groove is provided on one outer wall of the mounting plate 204, which is adapted to the abutment block 208.

[0025] like Figure 1 As shown, the mounting assembly 1 includes a base 101, a track 102, and a fixing plate 103. The track 102 is fixedly installed on the top of the base 101, and the fixing plate 103 is disposed above the track 102. The fixing plate 103 is welded to an external crane, and the upright plate 201 is fixedly installed on the top of the fixing plate 103.

[0026] like Figure 1 As shown, in some embodiments, the flipping assembly 3 includes a motor 301, two horizontal plates 302, two drive rods 303, two gears 304, two gears 305, a mounting bracket 306, and two anti-collision plates 307. The motor 301 is fixedly mounted on the top of the fixed plate 103. The two horizontal plates 302 are respectively fixedly mounted between the two vertical plates 201. The two drive rods 303 are respectively rotatably mounted on the two horizontal plates 302. The two gears 304 are respectively fixedly mounted on the ends of the two drive rods 303 that are far apart from each other. The two gears 305 are respectively fixedly sleeved on the two rotating rods 202. The gears 304 and 305 mesh with each other. The mounting bracket 306 is fixedly mounted on the two vertical plates. At the top of 201, both anti-collision plates 307 are fixedly mounted on the mounting bracket 306. More specifically, when the motor 301 is started, the motor 301 drives the drive rod 303 to rotate. The drive rod 303 rotates on the horizontal plate 302, and the drive rod 303 drives the first gear 304 to rotate. When the first gear 304 rotates, it meshes with the second gear 305, and the second gear 305 rotates due to the meshing transmission. The second gear 305 drives the rotating rod 202 to rotate, and the rotating rod 202 drives the rotating block 203 to rotate. The rotating block 203 drives the mounting plate 204 to move, and the mounting plate 204 drives the roller 207 to move and clamp the track 102. This has the advantages of flipping and moving, and clamping and braking the gantry crane.

[0027] In some embodiments, a soft rubber plate is fixedly installed on one outer wall of the anti-collision plate 307.

[0028] Working principle:

[0029] Step 1: Flip and move, start motor 301, motor 301 drives the drive rod 303 to rotate, drive rod 303 rotates on horizontal plate 302, drive rod 303 drives gear 1 304 to rotate, gear 1 304 meshes with gear 2 305 when rotating, gear 2 305 rotates due to meshing transmission, gear 2 305 drives rotating rod 202 to rotate, rotating rod 202 drives rotating block 203 to rotate, rotating block 203 drives mounting plate 204 to move, mounting plate 204 drives roller 207 to move and clamp track 102.

[0030] Step 2: Rail clamping braking. After the roller 207 is driven and clamps the rail 102, the movement of the gantry crane causes the roller 207 to roll. The roller 207 rolls on the rail 102, and the roller 207 drives the round rod 206 to rotate. The round rod 206 rotates on the support plate 205, and the roller 207 drives the abutment block 208 to rotate. The abutment block 208 rotates and moves closer to the rail 102 to fit. The abutment block 208 drives the fitting plate 209 to move and fit with the rail 102. At this time, the abutment block 208 and the roller 207 clamp the rail 102, initially braking the gantry crane. By the abutment block 208 fitting with the rail 102, an opposing force is applied to the direction of movement of the gantry crane, further braking it.
