Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a load-bearing rotatable tooling. Background Technology

[0002] Lifting equipment is a multi-functional mechanical device capable of vertical lifting and horizontal transport within a certain range, including electric forklifts, stacker trucks, mini cranes, and clamping vehicles.

[0003] However, current lifting equipment has the following main problems during use:

[0004] 1. To achieve angle adjustment during operation, existing equipment relies on rotating the crane frame. This operation causes the stress state of the entire crane frame and vehicle body to change with the rotation, resulting in uneven weight distribution and potentially causing the vehicle body to tip over. More importantly, even with this method, it is difficult to achieve 360° seamless, continuous, and smooth rotation adjustment.

[0005] 2. Existing equipment typically requires multiple hydraulic cylinders and guide rails to work together during lifting operations. This design not only increases the manufacturing cost of the equipment, but also accelerates the wear of the guide rails and hydraulic cylinders due to slight tolerance variations and component deformation during long-term use and in complex on-site environments, thereby shortening their service life.

[0006] Therefore, this utility model provides a lifting and rotating load-bearing device that can always maintain balance. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a load-bearing, rotatable tooling.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a load-bearing rotatable tooling, comprising:

[0009] The vehicle body and the crane frame placed on top of the vehicle body;

[0010] The lifting box is mounted on the side of the lifting frame via a connecting rod, and the bottom two sides of the lifting box are fixed to the vehicle body.

[0011] A hydraulic cylinder, which is mounted on the lifting box, is used to provide lifting power to achieve lifting.

[0012] A rotary reducer is installed at the bottom of the lifting box to provide rotational power and reduce speed, thereby driving rotation. A chassis is installed at the bottom of the rotary reducer.

[0013] In a preferred embodiment, four connecting rods are provided, and the four connecting rods are of the same length. Two connecting rods are arranged in a group, and the two groups of connecting rods are respectively connected to the lifting frame and the lifting box.

[0014] In a preferred embodiment, the crane box is provided with side plates on both sides, and the bottom of the side plates is fixed to the top of the vehicle body.

[0015] In a preferred embodiment, one end of each of the two sets of connecting rods is rotatably connected to the lifting frame, and the other end of each of the two sets of connecting rods is rotatably connected between the lifting box and the side plate.

[0016] In a preferred embodiment, connecting blocks are fixed to the inner top and inner bottom of the lifting box, and the top and end of the hydraulic cylinder are respectively mounted on the connecting blocks by bolts.

[0017] In a preferred embodiment, the hydraulic cylinder is mounted at an angle on two connecting blocks.

[0018] In a preferred embodiment, the lifting box is also equipped with a solenoid valve for controlling the opening and closing of the hydraulic cylinder.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] When the hydraulic cylinder initiates its extension and retraction, the movement of the cylinder, through its connection point with the crane box, causes the crane box to begin its oblique movement. As the crane box moves obliquely, the gyroscopic reducer and chassis at its bottom descend accordingly. When the chassis descends to a certain level and contacts the ground, the crane body and crane frame are gradually lifted away from the ground through the transmission of the crane box and connecting rods. When the extension and retraction of the hydraulic cylinder reaches a certain extent, the crane body and crane frame will be completely suspended in the air under the support of the chassis. When turning is required, the gyroscopic reducer is activated, causing the crane body and crane frame to rotate and change direction. The deceleration effect of the gyroscopic reducer ensures the smoothness of the rotation process and prevents instability caused by excessive rotation speed. Driven by the gyroscopic reducer, 360° rotation of the crane body and crane frame is achieved without dead angles. The lifting and lowering of the crane body and crane frame is achieved through the cooperation of the connecting rod and the crane box, avoiding the increased cost and wear caused by using multiple hydraulic cylinders and guide rails.

[0027] 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.

[0028] like Figures 1-4 As shown, this embodiment provides a technical solution: a load-bearing rotatable tooling, including: a vehicle body 1, a lifting frame 2 for lifting goods mounted on the top of the vehicle body 1, a lifting box 3 for lifting the vehicle body 1 and the lifting frame 2 mounted on the side of the lifting frame 2, the lifting box 3 being mounted on the side of the lifting frame 2 via a connecting rod 4, the bottom sides of the lifting box 3 being fixed to the vehicle body 1, a hydraulic cylinder 7 for providing lifting power being mounted on the lifting box 3, the extension and retraction of the hydraulic cylinder 7 causing the lifting box 3 to drive the vehicle body 1 and the lifting frame 2 to lift and lower, a rotary reducer 5 for providing rotational power and decelerating being rotatably mounted on the bottom of the lifting box 3 via a bearing, and a chassis 6 being fixed to the bottom of the rotary reducer 5.

[0029] Specifically, when hydraulic cylinder 7 starts to extend and retract, its movement, through its connection point with the lifting box 3, causes the lifting box 3 to begin to move obliquely. As the lifting box 3 moves obliquely, the rotary reducer 5 and chassis 6 at its bottom descend accordingly. When chassis 6 descends to a certain extent and contacts the ground, the vehicle body 1 and lifting frame 2 are gradually moved away from the ground through the transmission of lifting box 3 and connecting rod 4. When the extension and retraction of hydraulic cylinder 7 reaches a certain extent, the vehicle body 1 and lifting frame 2 will be completely suspended in the air under the support of chassis 6. When turning is required, the rotary reducer 5 is activated to rotate the vehicle body 1 and lifting frame 2 to change direction. The deceleration effect of the rotary reducer 5 ensures the smoothness of the rotation process and prevents the device from becoming unstable due to excessive rotation speed. Driven by the rotary reducer 5, the vehicle body 1 and lifting frame 2 can rotate 360° without dead angles. The lifting of the vehicle body 1 and the lifting frame 2 is achieved through the cooperation of the connecting rod 4 and the lifting box 3, avoiding the increased cost and wear caused by the need to use multiple hydraulic cylinders and guide rails.

[0030] like Figures 1-2 As shown, there are four or more connecting rods 4. All connecting rods 4 are of the same length. When using four connecting rods 4, they should be divided into two groups. The two groups of connecting rods 4 are rotatably connected to the two sides of the lifting box 3 and the lifting frame 2. When the hydraulic cylinder 7 extends or retracts, it causes the four connecting rods 4 to deform and rotate, thereby realizing the lifting and lowering of the vehicle body 1 and the lifting frame 2.

[0031] Among them, the two sets of connecting rods 4 located on both sides of the lifting frame 2 and the lifting box 3 are rotatably connected to the lifting frame 2 and the lifting box 3 through wear-resistant pins.

[0032] like Figure 4 As shown, side plates 9 are installed on both sides of the lifting box 3, and the bottom of the side plates 9 is fixed to the top of the vehicle body 1. The ends of the two sets of connecting rods 4 are rotatably connected between the lifting box 3 and the side plates 9. The side plates 9 strengthen the overall strength and prevent the lifting box 3 from deforming due to excessive force.

[0033] like Figure 4 As shown, connecting blocks are fixed to the inner top and bottom of the lifting box 3. The top and end of the hydraulic cylinder 7 are respectively bolted to the connecting blocks. The hydraulic cylinder 7 is installed by the connecting blocks arranged at the top and bottom. The hydraulic cylinder 7 is installed at an angle of 30°-50° on the two connecting blocks. By installing the hydraulic cylinder 7 at an angle, the hydraulic cylinder 7 can exert an oblique thrust on the lifting box 3 when it extends and retracts, thereby causing the lifting box 3 to lift the vehicle body 1 and the lifting frame 2.

[0034] like Figure 3 As shown, the lifting box 3 is also equipped with a solenoid valve 8 for controlling the opening and closing of the hydraulic cylinder 7. The solenoid valve 8 is electrically connected to the power system on the vehicle body 1. The extension and retraction of the hydraulic cylinder 7 are controlled by the solenoid valve 8.

[0035] Working principle:

[0036] like Figure 1-4 As shown:

[0037] The extension of the hydraulic cylinder 7 is controlled by the solenoid valve 8;

[0038] When hydraulic cylinder 7 starts to extend and retract, its movement, through its connection point with the lifting box 3, causes the lifting box 3 to begin to move obliquely. As the lifting box 3 moves obliquely, the rotary reducer 5 at its bottom and the chassis 6 descend accordingly. When the chassis 6 descends to a certain extent and contacts the ground, the vehicle body 1 and the lifting frame 2 are gradually lifted away from the ground through the transmission of the lifting box 3 and the connecting rod 4. When the extension and retraction of hydraulic cylinder 7 reaches a certain extent, the vehicle body 1 and the lifting frame 2 will be completely suspended in the air under the support of the chassis 6. When turning is required, the rotary reducer 5 is activated to rotate the vehicle body 1 and the lifting frame 2 to change direction.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. 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.
