Description

Technical Field

[0001] This utility model relates to a wedge rail device for lifting machinery, specifically a wind-resistant and anti-slip wedge rail device for lifting machinery, belonging to the field of lifting machinery technology. Background Technology

[0002] Lifting machinery refers to multi-action lifting machinery that vertically lifts and horizontally moves heavy objects within a certain range. Bridge cranes are lifting equipment that spans across workshops, warehouses, and material yards for material handling. The bridge frame of a bridge crane runs longitudinally along tracks laid on elevated structures on both sides, making full use of the space beneath the bridge frame for material handling. It is the most widely used and most numerous type of lifting machinery.

[0003] Utility model patent CN220264996U discloses a crane stop device, belonging to the field of crane machinery auxiliary accessories. It includes a rotating clamping mechanism, a wedge, and an extension plate. The bottom surface of the wedge is fixedly connected to the upper rear part of the extension plate. Limiting plates are connected to both sides of the bottom surface of the extension plate, which clamp the rail and use elastic force to keep the connecting rod in its initial position. Compared with existing technologies, it features safety and speed.

[0004] When using a bridge crane, it is necessary to position the crane in windy weather to prevent it from sliding or collapsing. Although the stop device in the aforementioned patent can prevent sliding, the clamping force of the limiting plate is relatively small. When the wind is strong, the rollers may detach from the rails, reducing the wind resistance of the crane. To address this issue, we provide a wind-resistant and anti-slip wedge rail device for cranes. Utility Model Content

[0005] Purpose of the invention: The purpose of this utility model is to provide a wind-resistant and anti-slip wedge rail device for lifting machinery in order to solve the problem that the rollers will fall off the rail when the wind force is strong in the prior art.

[0006] Technical solution: A wind-resistant and anti-slip wedge rail device for lifting machinery includes a steel rail and rollers. A support frame for fixing the rollers is provided on the surface of the steel rail. A clamping mechanism is provided at the upper end of the support frame. The clamping mechanism includes a power chamber, which is fixedly connected to the support frame. A lifting claw is slidably connected to the middle of the power chamber. The bottom end of the lifting claw engages with a protrusion on the steel rail. Two sets of wedge rail mechanisms are provided in the middle of the power chamber. Each wedge rail mechanism includes a wedge block, which abuts against the rollers.

[0007] Preferably, the lifting gripper extends into the power compartment and is threadedly connected to a first threaded rod, which is rotatably connected to the inner wall of the power compartment.

[0008] Preferably, an electric motor is fixedly installed on the upper surface of the power compartment, the electric motor is driven by the first threaded rod, and the power compartment is fixedly connected to the crane base.

[0009] Preferably, the wedge mechanism further includes a pressing block that abuts against the wedge block, and a second threaded rod is threadedly connected to the pressing block, wherein the first threaded rod and the second threaded rod are connected by a chain drive.

[0010] Preferably, the lower end of the extrusion block is provided with an inclined surface that abuts against the wedge block.

[0011] Preferably, a connecting frame is fixedly connected to the support frame, and a reset device connected to the wedge block is connected to the lower side of the connecting frame.

[0012] Preferably, the reset device includes a connecting block, a sliding frame is horizontally slidably connected to the connecting block, the sliding frame is connected to the wedge block, and a first telescopic spring is provided between the sliding frame and the connecting block.

[0013] Preferably, the side wall of the extrusion block is provided with a sliding rod, the connecting frame is provided with a limiting block that is slidably connected to the sliding rod, and the connecting block is provided with a sliding groove that is slidably connected to the sliding rod.

[0014] Preferably, a second telescopic spring is connected between the connecting frame and the connecting block.

[0015] Beneficial effects: This wind-resistant and anti-slip wedge rail device for lifting machinery uses a power chamber to position the lifting jaws, which then clamp the rails, firmly fixing the power chamber to the rail surface. This prevents the rollers from detaching from the rails, improving the wind resistance of the lifting machinery and thus enhancing its operational stability and safety. A connecting frame positions the connecting block, which in turn positions the wedge. The downward movement of the pressing block moves the wedge away from the connecting block, causing it to abut against the rollers and secure them, preventing them from sliding freely and improving the anti-slip performance of the lifting machinery.

[0016] 2. The wind-resistant and anti-slip wedge rail device for this lifting machinery uses the rotation of the first threaded rod to drive the lifting jaws to move up and down. The rotation of the power sprocket is controlled by the first threaded rod, and the rotation of the first threaded rod is controlled by the motor. The lifting jaws contact the protrusions of the rail to fix the power chamber to the rail, thereby improving the wind resistance of the lifting machinery. The rotation of the connecting sprocket is driven by the power sprocket to control the rotation of the second threaded rod, causing the pressing block to slide up and down. The second telescopic spring provides tension to the connecting block, preventing the connecting block from contacting the rail and improving the smoothness of the device during normal operation.

[0017] 3. The wind-resistant and anti-slip wedge rail device of this lifting machinery positions the wedge block through a sliding frame, keeping the wedge block and the connecting block moving horizontally and improving the stability of the wedge block's operation. Through the first telescopic spring, a thrust is provided to the sliding frame, causing the sliding frame to pull the wedge block back to its original position, improving the stability of the wedge block's reset. Through the limit block and sliding rod, the extrusion block is fixed to the surface of the connecting frame, improving the stability of the connecting frame's up and down sliding. Through the sliding groove and sliding rod, the extrusion block is fixed to the surface of the connecting block, improving the stability of the extrusion block's up and down sliding. Furthermore, through the sliding rod, limit block, and sliding groove, the connecting block can be prevented from moving outward, improving the stability of the extrusion block pushing the wedge block.

[0023] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0024] Please see Figure 1 and Figure 2The crane includes a rail 1 and rollers 2. A support frame 3 is provided on the surface of the rail 1 to fix the rollers 2. A clamping mechanism 4 is provided on the surface of the support frame 3. The clamping mechanism 4 is installed on the upper end face of the support frame 3. The clamping mechanism 4 includes a power chamber 401 and a power sprocket 405. The power chamber 401 is fixedly connected to the support frame 3. A lifting gripper 402 is slidably connected to the middle of the power chamber 401. The lifting gripper 402 is positioned by controlling the power chamber 401. The bottom end of the lifting gripper 402 engages with the protrusion of the rail 1. The lifting gripper 402 clamps the rail 1. The lower end of the lifting gripper 402 extends into the side groove of the I-beam rail 1, tightly fixing the power chamber 401 to the surface of the rail 1, preventing the rollers 2 from detaching from the rail 1, improving the wind resistance of the crane, and thus improving the stability and safety of the crane operation.

[0025] The lifting gripper 402 is threadedly connected to a first threaded rod 403. The power chamber 401 has a space inside. The first threaded rod 403 is installed inside the power chamber 401, and the top end of the first threaded rod 403 is rotatably connected to the power chamber 401. By rotating the first threaded rod 403, the lifting gripper 402 is driven to move up and down. During the up and down movement of the lifting gripper 402, it will disengage from the rail 1. Through the contact between the device body and the rail 1, the device and the rail can be fixed by the pulling force of the lifting gripper 402.

[0026] The bottom end of the first threaded rod 403 is fixedly connected to the power sprocket 405, and the rotation of the power sprocket 405 is controlled by the first threaded rod 403.

[0027] The power compartment 401 is fixedly connected to a motor 404 that controls the rotation of the first threaded rod 403. The motor 404 is fixedly installed on the upper side of the power compartment 401. The first threaded rod 403 and the motor 404 are drivenly connected. The power compartment 401 is fixedly connected to the crane base. By controlling the rotation of the first threaded rod 403 through the motor 404, the lifting gripper 402 is moved, and the power compartment 401 is fixed together with the rail 1, thereby improving the wind resistance of the crane machinery.

[0028] The electric motor 404 is existing technology. Those skilled in the art can select a suitable electric motor 404 for operation according to actual needs. This application will not go into detail about its detailed parameters and model.

[0029] Please see Figure 2 , Figure 3 and Figure 4Two sets of wedge rail mechanisms 5 are provided in the middle of the power compartment 401. The two sets of wedge rail mechanisms 5 are respectively located on both sides of the two rollers 2. The wedge rail mechanism 5 includes a connecting frame 501, a wedge block 502, a connecting block 503, and a pressing block 507. The connecting frame 501 is fixedly connected to the support frame 3 and is sleeved on the outside of the support frame 503. The connecting block 503 is connected to the bottom of the connecting frame 501 and the wedge block 502 is connected to the connecting block 503. The upper end surface of the wedge block 502 is provided with an arc surface. The arc surface of the wedge block 502 can extend into the bottom of the roller 2, thereby restricting the movement of the roller 2 and achieving the effect of restriction and fixation.

[0030] Furthermore, the extrusion block 507 is located above the wedge block 502, and the lower part of the extrusion block 507 is provided with an inclined surface, while the upper end of the wedge block 502 is provided with an inclined surface that cooperates with the extrusion block 507. By moving the extrusion block 507 downward, the wedge block 502 is moved, thereby engaging the roller 2.

[0031] The extrusion block 507 has a second threaded rod 508 internally threaded, and the second threaded rod 508 is rotatably connected to the power chamber 401. The top end of the second threaded rod 508 is fixedly connected to a connecting sprocket 509, while the first screw 403 is connected to a power sprocket 405. The connecting sprocket 509 is connected to the power sprocket 405 via a chain. The power sprocket 405 drives the connecting sprocket 509 to rotate, thereby controlling the rotation of the second threaded rod 508 and causing the extrusion block 507 to slide up and down.

[0032] The second threaded rod 508 has the opposite thread direction to the first threaded rod 403. When the first threaded rod 403 drives the lifting gripper 402 to move upward, the second threaded rod 508 drives the pressing block 507 to move downward. The diameter of the power sprocket 405 is larger than the diameter of the connecting sprocket 509. When the lifting gripper 402 contacts the protrusion of the rail 1, the pressing block 507 drives the wedge block 502 to collide with the roller 2.

[0033] A second telescopic spring 506 is fixedly connected to the surface of the connecting frame 501, and the bottom end of the second telescopic spring 506 is fixedly connected to the connecting block 503. A sliding frame 504 is slidably connected to the middle of the connecting block 503, and the sliding frame 504 is fixedly connected to the wedge block 502. The second telescopic spring 506 provides tension to the connecting block 503 to prevent the connecting block 503 from contacting the rail 1, thereby improving the smoothness of the device during normal operation. The sliding frame 504 positions the wedge block 502, so that the wedge block 502 and the connecting block 503 move horizontally, thereby improving the stability of the wedge block 502 during operation.

[0034] A first telescopic spring 505 is fixedly connected to the surface of the sliding frame 504, and the first telescopic spring 505 is fixedly connected to the connecting block 503. The first telescopic spring 505 provides a thrust to the sliding frame 504, so that the sliding frame 504 pulls the wedge block 502 back to its original position, thereby improving the stability of the wedge block 502's reset.

[0035] A sliding rod 510 is fixedly connected to the surface of the extrusion block 507. A limiting block 511 is fixedly connected to the middle of the connecting frame 501, and the sliding rod 510 is slidably connected to the limiting block 511. A sliding groove 512 adapted to the sliding rod 510 is opened in the middle of the connecting block 503. The extrusion block 507 is fixed to the surface of the connecting frame 501 by the limiting block 511 and the sliding rod 510, which improves the vertical sliding stability of the connecting frame 501. The extrusion block 507 is fixed to the surface of the connecting block 503 by the sliding groove 512 and the sliding rod 510, which improves the vertical sliding stability of the extrusion block 507. Furthermore, the sliding rod 510, the limiting block 511 and the sliding groove 512 can prevent the connecting block 503 from moving outward, which improves the stability of the extrusion block 507 pushing the wedge block 502.

[0036] In use, this invention works as follows: When it is necessary to fix the lifting machinery, the motor 404 controls the first threaded rod 403 to rotate, driving the lifting gripper 402 to move upward, so that the lifting gripper 402 contacts the protrusion of the rail 1, fixing the power chamber 401 to the rail 1 together, improving the wind resistance of the lifting machinery. At the same time, the first threaded rod 403 controls the power sprocket 405 to rotate, and the connecting sprocket 509 drives the second threaded rod 508 to rotate, controlling the pressing block 507 to slide downward and press the wedge block 502 away from the connecting block 503, pressing the wedge block 502 into the bottom of the roller 2, fixing the roller 2, preventing the roller 2 from sliding randomly, and improving the anti-slip performance of the lifting machinery. Through the above device, the lifting machinery is fixed and clamped, improving the wind resistance and anti-slip ability of the lifting machinery, and improving the protection of the lifting machinery.

[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
