Problems solved by technology

Although some jacking devices (such as scissor jacking devices) can adjust the jacking height, they need actuators such as hydraulic cylinders to provide holding force. Once the system loses power or fails, the holding force of the jacking device will fail to cause Dangerous, if you want to lock a jacking device such as a scissor jacking device in multiple positions, you need to set up an additional electric locking mechanism. This method requires additional actuators, which increases the complexity of control and the failure rate. will also rise

Embodiment 1

[0040] as attached Figure 3-4 The self-locking mechanism 1 shown, in addition to the sliding seat 11, also includes a rack 12, a transition block 13, a limit block 14, a driving block 15 and a driving unit 16 (the driving unit 16 is in the Figure 3-4 not shown in ); the rack 12 is fixedly installed, and has gear teeth 121 arranged in a horizontal linear array on it. Such as figure 2 As shown, the drive unit 16 is driven by the prime mover 3 through the lead screw 31 for translational movement.

[0041] A transition block 13 and a driving block 15 are slidably installed on the sliding seat 11 ; the sliding routes of the transition block 13 and the driving block 15 relative to the sliding seat 11 are vertical and horizontal respectively, and the movement of the two is related.

[0042] The limit block 14 is slidably installed on the transition block 13, and the two slide relatively vertically; the limit block 14 has a forward tooth portion 141, and the forward tooth portion...

Embodiment 2

[0048] In the first embodiment, when the sliding seat 11 is driven to move in the first direction A, there is a problem that every time the sliding seat 11 moves a tooth pitch (the distance between two adjacent gear teeth 121), the limit block 14 Resetting under gravity and the thrust of the first spring 17 blocks the sliding seat 11 again so that it cannot move. Therefore, when the target movement distance of the sliding seat 11 is greater than the tooth pitch, it will go through an unlocking process every time it passes through a gear tooth 121, resulting in movement. The process is not very continuous. In order to solve this technical problem, some improvements are made in this embodiment on the basis of the first embodiment.

[0049] Such as Figure 5 and Figure 7 As shown, in this embodiment, the connection mode between the rack 12, the transition block 13, the limit block 14, and the drive block 15 of the self-locking mechanism 1 is the same as that of the first embodi...

Embodiment 3

[0059] This embodiment provides a handling robot, such as Figure 11 As shown, it includes a mobile chassis 4, a functional component 5 and the above-mentioned jacking device, and the self-locking mechanism 1 included in the jacking device can be the self-locking mechanism 1 in the first embodiment or the self-locking mechanism in the second embodiment 1. The jacking device is installed on the mobile chassis 4, and the functional component 5 is installed on the top of the jacking device. The functional assembly 5 shown in the figure is a telescopic fork for obtaining goods. In other embodiments, the functional assembly 5 can also be a tray, a conveying roller, etc., and the functional assembly 5 can be configured on demand. Since it is not the protection focus of the present invention, I won't introduce it too much here.

Abstract

The invention discloses a self-locking mechanism of a jacking device, the jacking device and a transfer robot. The self-locking mechanism comprises a sliding base, a rack and a driving unit, wherein blocking teeth are arranged on the rack; a transition block and a driving block are installed on the sliding base in a sliding mode; a limiting block is installed on the transition block in a sliding mode; the limiting block is provided with a forward tooth part, and the forward tooth part and the blocking teeth can stop the sliding base from moving in the first direction and do not stop the sliding base from moving in the second direction in the matched state; and the driving unit drives the transition block to ascend and descend through the driving block so that the limiting block and the rack can be switched between the matched state and the disengaged state. The self-locking mechanism of a special structure is arranged between the driving end of the lifting mechanism and a driving link, so that the position of the sliding base can be locked at each blocking tooth position, the lifting mechanism can stably keep goods at various height positions, and the self-locking mechanism and the lifting mechanism share the same power source, so that the control complexity of a system is not increased.

Description

technical field [0001] The invention relates to the technical field of storage and handling robots, in particular to a self-locking mechanism of a jacking device, a jacking device and a handling robot. Background technique [0002] Handling robots are now widely used in the field of warehousing and logistics. They are used to move warehousing materials, which can greatly improve the efficiency of material circulation. The jacking device is the core component of the storage robot. In the prior art, the jacking device can only keep the lifted heavy objects at a fixed jacking height and maintain stability at the jacking height. Although some jacking devices (such as scissor jacking devices) can adjust the jacking height, they need actuators such as hydraulic cylinders to provide holding force. Once the system loses power or fails, the holding force of the jacking device will fail to cause Dangerous, if you want to lock a jacking device such as a scissor jacking device in multi...
