Description

Technical Field

[0001] The utility model relates to the technical field of lifting frames, in particular to a detachable square lifting frame. Background Art

[0002] Lifting frames are mainly used in various industrial, construction and warehousing environments. When installing or repairing equipment, the lifting frame can be used to lift the equipment to an appropriate position, and generally includes a driving mechanism, a telescopic mechanism and a tabletop.

[0003] For example, a lifting frame for building construction with a protection function disclosed in the prior art Chinese Patent Publication No. "CN114607130B" has a structure including a support base, a cylinder, a folding lifting plate and a standing mechanism. The upper end surface of the support base is hinged to the lower end of the cylinder, and the output end of the cylinder is hinged to the inner side of the folding lifting plate. During the extrusion of the telescopic hose, the internal air pressure changes, and moisture is squeezed into the telescopic hose. The blade rotates around the positioning ball for positioning, and the moisture inside the telescopic hose is turned into a mist state and sprayed out, so that the surrounding static electricity is conducted to the humid air, avoiding the direct conduction of static electricity to the workers' bodies.

[0004] However, in the prior art, most of the detachable square lifting frames generally adopt traditional fixing structures such as bolts between the plate surface and the mounting frame. This leads to cumbersome operation during the disassembly process after the plate surface is damaged, not only consuming time but also having low efficiency, making the disassembly and assembly of the lifting frame not convenient and efficient enough. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art, and to propose a detachable square lifting frame.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Design a detachable square lifting frame, including a base, an installation frame is arranged above the base, a plate is arranged on the end surface of the installation frame, several lifting rods are arranged between the installation frame and the base, and a buffer assembly is sleeved on the circumferential surface of the lifting rods;

[0008] Wherein, clamping assemblies for clamping the plate are further arranged on both sides of the lower end of the installation frame, and a driving device for driving the installation frame () to move up and down is installed on the upper end of the base.

[0009] Further, the lifting rod includes a round rod and a sleeve;

[0010] The round rod is fixedly connected to the upper end surface of the base;

[0011] The sleeve is sleeved on the circumferential surface of the round rod, and the upper end of the sleeve is fixedly connected to the lower side of the mounting bracket.

[0012] Furthermore, the buffer assembly includes a compression spring sleeved on the circumferential surface of the round rod. The upper and lower ends of the compression spring are respectively fixedly connected with a bottom plate and a sliding plate. The bottom plate is fixedly connected to the lower end of the round rod, and the sliding plate is slidably connected to the round rod.

[0013] Furthermore, the clamping assembly includes two mounting blocks fixedly connected to the mounting bracket. The mounting blocks are symmetrically distributed. A rod is slidably connected inside the mounting block. The upper end of the rod is fixedly connected with a clamping block. A guiding inclined surface is provided on the lower side of the rod. The upper end of the rod is fixedly connected with a baffle plate, and a spring is fixedly connected between the baffle plate and the mounting block.

[0014] Furthermore, the clamping assembly further includes two U-shaped frames fixedly connected to the base. The two U-shaped frames are respectively arranged on the lower sides of the two guiding inclined surfaces. A wheel member is rotatably connected to the center of the U-shaped frame.

[0015] Furthermore, slots adapted to the clamping blocks are provided at both ends of the plate, and the clamping blocks are clamped in the slots.

[0016] For the detachable square lifting frame proposed by the present utility model, the beneficial effects are as follows: In this embodiment, the plate is firmly fixed through the clamping assembly. As the mounting bracket slowly rises, the clamping assembly tightly holds the plate to ensure its safety and stability during the operation. When the mounting bracket completes its mission and descends smoothly, the clamping assembly will automatically release, making the taking and placing of the plate easy and convenient, greatly improving the operation efficiency and safety.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1-4 , a detachable square lifting frame, including a base 1, an upper part of the base 1 is provided with a mounting frame 11, an end face of the mounting frame 11 is provided with a plate 10, and a plurality of lifting rods 2 are provided between the mounting frame 11 and the base 1; a buffer assembly 3 is sleeved on the circumferential surface of the lifting rod 2;

[0024] Among them, clamping assemblies 4 for clamping the plate 10 are further provided on both sides of the lower end of the mounting frame 11, and a driving device 12 for driving the mounting frame 11 to move up and down is installed on the upper end of the base 1. The driving device 12 is a cylinder, and the telescopic end of the cylinder is fixedly connected to the mounting frame 11.

[0025] Furthermore, the lifting rod 2 includes a round rod 21 and a sleeve 22;

[0026] The round rod 21 is fixedly connected to the upper end face of the base 1;

[0027] The sleeve 22 is sleeved on the circumferential surface of the round rod 21, and the upper end of the sleeve 22 is fixedly connected to the lower side of the mounting frame 11.

[0028] In this embodiment, the buffer assembly 3 includes a compression spring 31 sleeved on the circumferential surface of the round rod 21. The upper and lower ends of the compression spring 31 are respectively fixedly connected with a bottom plate 32 and a sliding plate 33. The bottom plate 32 is fixedly connected to the lower end of the round rod 21, and the sliding plate 33 is slidably connected to the round rod 21. When the mounting frame 11 moves downward, the sleeve 22 also descends. When it descends to a certain height, the bottom of the sleeve 22 will contact the sliding plate 33, and the compression spring 31 buffers the descent of the sleeve 22, so that it will not fall directly during the descent and damage the parts.

[0029] Among them, the clamping assembly 4 includes two mounting blocks 13 fixedly connected to the mounting frame 11. The mounting blocks 13 are symmetrically distributed. A rod 41 is slidably connected within the mounting blocks 13. A clamping block 42 is fixedly connected to the upper end of the rod 41. A guiding inclined surface 46 is formed on the lower side of the rod 41. A baffle 48 is fixedly connected to the upper end of the rod 41. A spring 43 is fixedly connected between the baffle 48 and the mounting block 13. A square rod is provided in the middle of the mounting block 13. A channel is formed on the rod 41. The square rod is slidably connected within the channel. The square rod is a square rod, so that the rod 41 can only slide through the square rod and the mounting block 13 and cannot rotate.

[0030] It should be noted that the clamping assembly 4 further includes two U-shaped frames 44 fixedly connected to the base 1. The two U-shaped frames 44 are respectively disposed on the lower sides of the two guiding inclined surfaces 46. A wheel member 45 is rotatably connected to the center of the U-shaped frame 44. The guiding inclined surface 46 is slidably connected to the wheel member 45. When the mounting frame 11 descends and the guiding inclined surface 46 abuts against the wheel member 45, the rod 41 moves outward, causing the clamping block 42 to leave the slot 101 of the plate 10, so as to achieve the effect of facilitating taking. When the mounting frame 11 ascends, the force of the guiding inclined surface 46 abutting against the wheel member 45 is cancelled, and the rod 41 contracts through the tension of the spring 43, so that the clamping block 42 clamps the slot 101 of the plate 10 again.

[0031] On the basis of the above embodiment, slots 101 adapted to the clamping blocks 42 are provided at both ends of the plate 10, and the clamping blocks 42 are clamped in the slots 101.

[0032] Working mode; during work, the mounting frame 11 is placed at the lowest position, and then the plate 10 is placed on the mounting frame 11 so that the slot 101 of the plate 10 aligns with the clamping block 42. The driving device 12 is turned on to make the mounting frame 11 ascend. At this time, the force of the guiding inclined surface 46 abutting against the wheel member 45 is cancelled, and the rod 41 contracts through the tension of the spring 43. Therefore, the clamping block 42 is clamped with the slot 101 of the plate 10 to achieve the clamping and fixing effect. When the work is over, the mounting frame 11 is lowered through the driving device 12, the guiding inclined surface 46 abuts against the wheel member 45, the rod 41 moves outward, and the clamping block 42 leaves the slot 101 of the plate 10, so as to achieve the effect of facilitating taking.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
