[0002] A lifting platform is a lifting machine that transports people or objects vertically. It also refers to equipment for vertical transportation in logistics systems such as factories and automatic warehouses. The lifting platform is often equipped with various flat conveying equipment as a connecting device for conveyor lines at different heights.

[0003] In the related art, a storage rack is fixedly connected to the circumferential outer wall of the lifting workbench, and the storage rack is used to place some operating tools.

[0004] The prior art still has the following problems: due to different habits of operators, the positions of work tools are different, and the required placement positions of the racks are also different. The racks are usually welded on the workbench and cannot be moved, so there is still room for improvement. Utility Model Content

[0005] In order to improve the situation that different operators have different tool placement habits and require different placement positions of storage racks, and the storage racks are usually welded and cannot be moved, the present application provides a lifting workbench.

[0006] The present application provides a lifting workbench adopting the following technical solution:

[0007] A lifting workbench comprises a table body, a storage rack installed on the circumferential side wall of the table body, and a hand screw for fixing the storage rack, wherein the storage rack is fixedly connected to a slider on a side close to the table body, and a first slide groove opened along the length direction of the table body is provided on the side wall of the table body, the slider is slidably connected to the first slide groove, and a limit block limiting the movement of the slider in a vertical direction is fixedly connected to the side of the slider away from the storage rack, the limit block is slidably connected to the first slide groove, a threaded hole is provided on the storage rack, the hand screw is threadedly connected to the threaded hole, and the hand screw extends out of one side of the threaded hole and abuts and presses against the side wall of the table body.

[0008] By adopting the above technical solution, when the storage rack is moved to the position required by the operator, the operator rotates the hand screws and presses the hand screws onto the table body to complete the fixation of the storage rack, thereby increasing the convenience of fixing and installing the storage rack. At the same time, the position of the storage rack is adjusted according to the operator's habits, thereby improving the operator's work efficiency.

[0009] Optionally, a baffle covering the opening of the first sliding groove is provided on the platform.

[0010] By adopting the above technical solution, when the hand screws are not tightened, the operator collides with the rack, and the rack is likely to slide from the opening of the first slide slot, thereby causing damage. The setting of the baffle restricts the movement of the rack, reduces the probability of damage to the rack, and improves safety.

[0011] Optionally, a mounting frame is fixedly connected to the side wall of the platform, the mounting frame is provided with a movable groove for the baffle to slide, the movable groove is connected to the first sliding groove, and the side of the mounting frame away from the platform is provided with a first groove for the slider and the limit block to move out.

[0012] By adopting the above technical solution, when the operator needs to cover the opening of the first slide slot, the baffle is moved to the opening, thereby reducing the probability of the baffle being lost; at the same time, when the operator slides the storage rack out of the first slide slot, the slider and the limit block pass through the first groove, thereby reducing the interference of the mounting frame on the storage rack and improving convenience.

[0013] Optionally, a first shifting rod is fixedly connected to a side of the baffle away from the side wall of the platform, a second groove for the first shifting rod to slide is reserved on a side of the mounting frame away from the platform, and the first groove is connected to the second groove.

[0014] By adopting the above technical solution, when the baffle needs to cover or open the opening of the first slide groove, the operator moves the first lever to slide the baffle in the mounting frame, which reduces the operating difficulty and improves the working efficiency of the operator.

[0015] Optionally, a first through hole is provided on the mounting frame, a second through hole is provided on the baffle, the first through hole and the second through hole are located on the same straight line, a penetration rod is provided on the platform, and the penetration rod is sequentially penetrated into the first through hole and the second through hole.

[0016] By adopting the above technical solution, when the penetration rod is penetrated through the first through hole and the second through hole in sequence, the penetration rod fixes the baffle at the opening of the first slide groove, thereby reducing the probability of the baffle moving left and right and being unable to cover the opening due to vibration when the platform is raised or lowered, thereby enhancing the overall safety.

[0017] Optionally, a compression spring is provided on the platform body for driving the penetration rod to move toward the direction close to the baffle, and a second slide groove for placing the compression spring is also provided on the side wall of the platform body, the second slide groove is connected to the movable groove, the penetration rod is slidably connected in the second slide groove, one side of the compression spring abuts against the side wall of the second slide groove, and the other side of the compression spring abuts against one side of the side wall of the penetration rod close to the second slide groove.

[0018] By adopting the above technical solution, when one end of the penetration rod embedded in the second slide groove abuts against the compression spring, the compression spring provides an elastic force to the penetration rod after being compressed, driving the penetration rod to penetrate the first through hole and the second through hole, thereby completing the tightening action, reducing the operating steps of the operator and improving the operating efficiency.

[0019] Optionally, a convex column for the compression spring to be sleeved is fixedly connected to the platform, the convex column is integrally embedded in the second sliding groove, and the penetration rod is sleeved and slidably connected to the convex column.

[0020] By adopting the above technical solution, when the compression spring is sleeved on the convex column, the convex column limits the moving direction of the compression spring, reduces the risk of the compression spring being twisted in the second slide groove due to uneven force, thereby failing to complete the action of abutting the penetration rod, or popping out of the second slide groove, and improves the stability of the movement of the compression spring.

[0021] Optionally, a second shifting rod is fixedly connected to a side of the penetration rod away from the bottom wall of the second sliding groove, and the second shifting rod protrudes out of the plane where the side wall of the platform is located.

[0022] By adopting the above technical solution, when the penetration rod is penetrated into the first through hole and the second through hole by the force of the compression spring, the second lever abuts against the side wall of the second slide groove, thereby limiting the moving distance of the penetration rod and avoiding the problem of the penetration rod slipping and falling due to the force; at the same time, the setting of the second lever is convenient for the operator to move, reducing the difficulty of operation.

[0023] Optionally, the penetrating rod is sleeved on the concave hole on the convex column and is connected to the outside.

[0024] By adopting the above technical solution, when the concave hole on the penetration rod is connected to the outside, it is convenient for operators to install the penetration rod, thereby reducing the difficulty of installing the penetration rod and improving assembly efficiency.

[0025] Optionally, it also includes a driving motor, a control device, a rising device, a descending device and a driving device for controlling the platform to rise and fall;

[0026] The control device is connected to the ascending device and the descending device, and the control device is used to close the power supply circuit of the ascending device or the descending device;

[0027] The ascending device, the descending device and the driving device are connected, and when the control device closes the power supply circuit of the ascending device, the ascending device outputs an ascending signal to the driving device; when the control device closes the power supply circuit of the descending device, the descending device outputs a descending signal to the driving device;

[0028] The driving device is connected to the driving motor, and the driving device controls the driving motor to rotate forward in response to an ascending signal, and controls the driving motor to rotate reversely in response to a descending signal;

[0029] When the control device turns on the power supply circuit of the ascending device, the ascending device outputs an ascending signal to the driving device, and the driving device controls the driving motor to rotate forward;

[0030] When the control device turns on the power supply circuit of the descending device, the descending device outputs a descending signal to the driving device, and the driving device controls the driving motor to reverse.

[0031] By adopting the above technical scheme, the control device turns on the power supply circuit of the ascending device or the power supply circuit of the descending device, the ascending device outputs an ascending signal to the driving device, and the descending device outputs a descending signal to the driving device. The driving device receives the ascending signal to control the driving motor to rotate forward, and the driving device receives the descending signal to control the driving motor to rotate reversely, thereby controlling the lifting and lowering action of the platform body by the forward and reverse rotation of the driving motor, reducing the operating difficulty and improving the convenience of lifting and lowering the platform body.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. The operator rotates the hand screws and presses them against the table to fix the rack, which increases the convenience of the rack installation. At the same time, the position of the rack is adjusted according to the operator's habits, thereby improving the operator's work efficiency.
