Description

Technical Field

[0001] The utility model relates to the technical field of axle clamping, and particularly relates to a falling - proof axle clamp. Background Art

[0002] Axle clamping devices have important applications in industrial production and maintenance. Their main function is to firmly clamp the axle to ensure safety and convenience during the operation. In the prior art, most axle clamping devices adopt simple fixing methods and lack effective anti - dropping designs, which easily lead to accidental slipping of the axle during the operation, increasing safety risks.

[0003] Existing axle clamping devices usually adopt a single fixing mechanism, such as a simple clamping device or a support frame. These devices lack stability and safety during the fixing process of the axle. For example, some devices only fix the axle through clamping force and cannot effectively prevent the axle from dropping during flipping or moving. The main defects of the prior art are the lack of an effective anti - dropping mechanism and flexibility, resulting in potential safety hazards and inconvenient operations in practical applications. Content of the Utility Model

[0004] The purpose of the utility model is to provide a falling - proof axle clamp to solve the problem that the axle is likely to drop during the operation of the existing axle clamping devices.

[0008] By adopting the above technical solution, the universal wheels at the bottom of the lift enable the clamp to move flexibly, and the bracket is fixed at the lifting end to ensure the stability of the axle during the operation. The rotatable arrangement of the flipping mechanism enables the axle to rotate, and the fixed arrangement of the limiting mechanism effectively prevents the axle from dropping during flipping, improving the safety and convenience of the operation.

[0009] Furthermore, the bracket is in a U - shape, the bottom of the bracket is fixedly arranged at the lifting end of the lift, and the flipping mechanism is rotatably arranged on the upper parts of the two side walls of the bracket.

[0010] By adopting the above technical solution, the design of the U-shaped bracket increases the stability of the bracket, and the rotation of the flipping mechanism is set on the upper part of the side wall, which makes the flipping of the axle more flexible and further enhances the anti-drop ability of the clamp.

[0011] Furthermore, the flipping mechanism includes a rotating shaft rotatably arranged on the two side walls of the bracket and a flip plate fixedly arranged on the two rotating shafts, wherein one of the rotating shafts extends out of the bracket, and a handwheel is fixedly arranged on one end of the rotating shaft extending out of the bracket.

[0012] By adopting the above technical solution, the design of the flipping mechanism makes the flipping of the axle more convenient, and the setting of the handwheel facilitates the operator to perform manual control, thereby improving the convenience and flexibility of operation.

[0013] Furthermore, the limiting mechanism includes a first column and a second column vertically arranged on the flap, and a blocking frame slidably arranged on the first column. The blocking frame is clamped with the second column, and there are two first columns and two second columns respectively.

[0014] By adopting the above technical solution, the design of the limiting mechanism effectively limits the movement range of the axle, and the clamping design of the blocking frame and the second column increases the stability of the limit, ensuring that the axle will not accidentally slip during the flipping process.

[0015] Furthermore, a locking piece is fixedly provided at the bottom of the blocking frame, the locking piece is engaged with the second column, the axle is placed on the flap, and the first column, the second column and the blocking frame block the axle on the flap.

[0016] By adopting the above technical solution, the clamping design of the locking member and the second column makes the fixation of the axle on the flap more stable, and the combined use of the first column, the second column and the blocking frame further enhances the anti-falling ability of the axle.

[0017] Furthermore, the blocking frame is composed of two crossbeams slidably arranged on the two first columns and a connecting beam fixedly arranged between the two crossbeams, and the locking member is fixedly arranged on the connecting beam.

[0018] By adopting the above technical solution, the design of the blocking frame makes the fixation of the axle on the flap more stable, and the combined use of the cross beam and the connecting beam increases the strength and stability of the blocking frame.

[0019] Furthermore, the locking member includes a mounting seat fixedly arranged on the connecting beam, a pin shaft slidably arranged on the mounting seat, and a pin hole opened on the side of the second column, and the pin shaft is clamped in the pin hole.

[0021] Furthermore, a placement groove is provided on the first column, a fixed shaft is transversely provided in the placement groove, and a sliding groove is provided on the crossbeam, and the sliding groove slides along the fixed shaft.

[0022] By adopting the above technical solution, the design of the placement groove and the fixed axis on the first column makes the sliding of the beam more stable, and the sliding design of the slide groove along the fixed axis increases the flexibility of the beam, ensuring the stability of the axle during the flipping process.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] This embodiment relates to an anti-drop axle clamp, the overall structure of which is as follows: Figure 1 As shown, it includes a lift 1, a bracket 2, a turning mechanism 3, and a limiting mechanism 4.

[0044] Among them, a universal wheel 5 for walking is fixedly set at the bottom of the elevator 1; the bracket 2 is fixedly set at the lifting end of the elevator 1, and the axle is placed on the bracket 2; the turning mechanism 3 is rotatably set on the bracket 2, and the axle rotates with the turning mechanism 3; the limiting mechanism 4 is fixedly set on the turning mechanism 3, and the axle is located inside the limiting mechanism 4.

[0045] It is worth mentioning that the design of the universal wheel 5 is to facilitate the movement of the clamp, thereby facilitating the adjustment of the position of the axle. The lift 1 is a common lifting device in the prior art, and its purpose is to drive the axle up and down, so as to facilitate the pulling of the car to the bottom of the car body. It will not be repeated here. The setting of the bracket 2 facilitates the installation of the flipping mechanism 3. The flipping mechanism 3 can drive the axle to rotate the angle, increase the flexibility of installing the axle, and the limiting mechanism 4 can fix the axle on the flipping mechanism 3 to prevent the axle from falling during flipping or moving, thereby causing danger and axle damage.

[0046] Based on the overall introduction above, an exemplary structure of the anti-drop axle clamp of this embodiment is as follows: Figure 2 As shown, the bracket 2 is in the shape of a U-shaped bracket. The bottom of the bracket 2 is fixedly mounted on the lifting end of the elevator 1, and the flip mechanism 3 is rotatably mounted on the upper portions of the two side walls of the bracket 2. Specifically, the bracket 2 is configured in the U-shaped bracket to facilitate the rotation of the flip mechanism 3 within the bracket 2. In other words, the flip mechanism 3 is mounted on the two side walls of the bracket 2. Reinforcing ribs can be welded between the bottom of the bracket 2 and the two side walls to increase the strength of the bracket 2. The bottom of the bracket 2 can be mounted on the lifting platform of the elevator 1 using screws, thereby enabling the flip mechanism 3 to be raised and lowered.

[0047] As a preferred embodiment, Figure 2 As shown, in this embodiment, the flipping mechanism 3 includes a rotating shaft 301 rotatably arranged on the two side walls of the bracket 2, and a flip plate 302 fixedly arranged on the two rotating shafts 301, one of the rotating shafts 301 extends out of the bracket 2, and a hand wheel 303 is fixedly arranged on one end of the rotating shaft 301 extending out of the bracket 2.

[0048] It should be noted that the two rotating shafts 301 rotate horizontally on the upper part of the two side walls of the bracket 2, and the flap 302 flips along with the two rotating shafts 301. The rotating shaft 301 can be connected to the bracket 2 through a bearing, and the flap 302 is driven to rotate by rotating the handwheel 303. Of course, in order to improve the automation of the equipment, the handwheel 303 can also be replaced with a stepper motor, and the flap 302 is driven to rotate by the stepper motor. Since the stepper motor is a common driving component in the prior art, it is not mentioned in the accompanying drawings.

[0049] As a preferred embodiment, Figure 3As shown, in this embodiment, the limiting mechanism 4 includes a first column 401 and a second column 402 vertically mounted on the flap 302, and a blocking frame 403 slidably mounted on the first column 401. The blocking frame 403 is engaged with the second column 402, and there are two of each of the first column 401 and the second column 402. A locking member 404 is fixedly mounted at the bottom of the blocking frame 403, and the locking member 404 is engaged with the second column 402. When the axle is placed on the flap 302, the first column 401, the second column 402, and the blocking frame 403 block the axle on the flap 302.

[0050] It should be noted that the two first columns 401 and the two second columns 402 are respectively arranged parallel to the length direction of the flap 302, and the first column 401 and the second column 402 are arranged opposite to each other, and the length direction of the axle is parallel to the length direction of the flap 302, that is, the axle is located between the first column 401 and the second column 402, and the blocking frame 403 is located at the top of the first column 401 and the second column 402, which can block the axle between the first column 401 and the second column 402 to prevent it from falling. One end of the blocking frame 403 can be rotatably connected to the first column 401, and the other end is clamped with the second column 402 by a locking member 404. This arrangement makes it convenient to place the axle between the first column 401 and the second column 402, and the flap 302 and the blocking frame 403 are located at the lower and upper parts of the axle. This arrangement can restrict the axle, and it will not fall regardless of whether the axle moves or flips.

[0051] As a preferred Figure 4 As shown, the blocking frame 403 of this embodiment is composed of two crossbeams 4031 slidably mounted on the two first columns 401, and a connecting beam 4032 fixedly mounted between the two crossbeams 4031. The locking member 404 is fixedly mounted on the connecting beam 4032. The first columns 401 are provided with a placement slot 4033, within which a fixed shaft 4034 is transversely mounted. The crossbeam 4031 is provided with a slide slot 4035 that slides along the fixed shaft 4034.

[0052] Specifically, the crossbeam 4031 can rotate and slide on the first column 401. When the axle needs to be placed, it is only necessary to pull the crossbeam 4031 to separate the crossbeam 4031 from the second column 402, which is convenient for placing the axle. In addition, due to the sliding setting, after the axle is close to the vehicle body, it is also only necessary to pull the crossbeam 4031 to release the axle, which is convenient for installation on the vehicle body. The connecting beam 4032 is installed at one end of the crossbeam 4031 close to the second column 402. Its purpose is to facilitate the engagement of the locking member 404 with the second column 402. 4031, it is only necessary to separate the locking piece 404 and the second column 402 to pull out the beam 4031. The beam 4031 slides in the placement groove 4033 of the first column 401 to improve the stability of the beam 4031 when sliding. The fixed shaft 4034 is inserted in the sliding groove 4035. If the locking piece 404 and the second column 402 are engaged, the fixed shaft 4034 can ensure that the beam 4031 will not be pulled out from the placement groove 4033, that is, the fixed shaft 4034 can ensure that the beam 4031 slides along the fixed shaft 4034.

[0053] As a preferred Figure 5 As shown, the locking member 404 of this embodiment includes a mounting seat 4041 fixedly mounted on the connecting beam 4032, a pin 4042 slidably mounted on the mounting seat 4041, and a pin hole 4043 defined on the side of the second column 402, with the pin 4042 being engaged in the pin hole 4043. Specifically, the mounting seat 4041 is fixedly mounted on the connecting beam 4032 by screws, the mounting seat 4041 defines a through hole, the pin 4042 slides in the through hole, a handle is rotatably mounted on the mounting seat 4041, and the pin 4042 and the handle are connected by a connecting rod. This arrangement facilitates the sliding of the pin 4042. The pin 4042 slides into the pin hole 4043 of the second column 402, at which point it is engaged, and the axle can be restrained in the limiting mechanism 4. The pin 4042 slides in the opposite direction, separating the pin 4042 from the second column 402, thereby facilitating the placement and removal of the axle from the limiting mechanism 4.

[0054] The anti-drop axle clamp in this embodiment is designed with a universal wheel 5 at the bottom of the lift 1, so that the clamp can be moved flexibly, thereby improving the convenience of operation; the design of the U-shaped bracket 2 and the flip mechanism 3 enhances the fixing stability of the axle, ensures that the axle can be adjusted in angle, and improves flexibility; the design of the limiting mechanism 4 and the locking member 404 effectively prevents the axle from accidentally slipping during operation, thereby improving the safety of operation.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
