Description

TECHNICAL FIELD

[0001] The utility model relates to the technology field of stacking machine especially relates to a stacking machine speed limiting steel wire rope tensioning device and speed limiting system. BACKGROUND

[0002] In modern warehousing management, the stacking machine is widely used as the core logistics equipment of the automatic stereoscopic warehouse. The speed limiting system is an important part of the safety components of the stacking machine, which is mainly composed of a speed limiter, a safety clamp, a steel wire rope and a tensioning device. The speed limiter is installed at the top of the stacking machine, and the tensioning device is installed at the bottom of the stacking machine. The steel wire rope is in a closed loop form and is wound between the speed limiter, the safety clamp and the tensioning device. The tensioning device makes the steel wire rope tightly wind in the speed limiter, so that the speed limiting steel wire rope and the stacking machine fork move synchronously at all times. The main function of the tensioning device is to generate tension on the speed limiter steel wire rope and prevent the speed limiter steel wire rope from swinging during operation to avoid interference and entanglement with other components.

[0003] At present, most of the tensioning devices on the market use counterweight or tension spring to tension. However, as the lifting height of the stacking machine increases, the weight of the tensioning device needs to be increased to tension the speed limiter steel wire rope, which will lead to an increase in the size of the tensioning device and a corresponding increase in the installation space. Moreover, as the stacking machine moves at high speed, the counterweight will swing due to inertia, causing the steel wire rope to loosen and shake or loosen and disengage from the tensioning wheel groove. When the stacking machine fork falls at an excessive speed and needs to be braked by the safety clamp, the lack of tensioning force will cause the speed limiter and the safety clamp to fail to work together, resulting in danger.

[0047] The following will be described in combination with Figures 1 to 3The stacking machine speed limiting steel wire rope tensioning device and the speed limiting system provided by the embodiments of the utility model are described in detail through specific embodiments and application scenarios.

[0048] In a first aspect, as shown in Figure 1 and Figure 2 The embodiments provide a stacking machine speed limiting steel wire rope tensioning device 1, which comprises a mounting seat 11, a sliding seat 12, a tensioning pulley 13 and an elastic member 14.

[0049] The mounting seat 11 is arranged at the bottom of the stacking machine.

[0050] The tensioning pulley 13 is rotatably arranged on the sliding seat 12, and the bottom end of the steel wire rope 2 is arranged on the tensioning pulley 13.

[0051] The elastic member 14 is clamped between the sliding seat 12 and the mounting seat 11, and the elastic member 14 is configured to be in a compressed state relative to the mounting seat 11 to apply an elastic force to the sliding seat 12 to tension the steel wire rope 2.

[0052] It can be understood that when the lifting height of the stacking machine is large and the lifting speed is fast, the tensioning requirement of the steel wire rope 2 is high, so that the steel wire rope 2 can be linked with the speed limiter and the safety clamp at any time to quickly brake the fork of the stacking machine.

[0053] The mounting seat 11 of the embodiments is used for fixedly connecting with the bottom cross beam of the stacking machine to form a stable fixed position.

[0054] The sliding seat 12 is used for mounting the tensioning pulley 13, the tensioning pulley 13 is arranged on the steel wire rope 2, and the tensioning pulley 13 can rotate relative to the sliding seat 12, so that the steel wire rope 2 can move relative to the tensioning pulley 13, thereby driving the synchronous movement of the fork.

[0055] The sliding seat 12 can move up and down relative to the mounting seat 11 to adjust the position of the sliding seat 12 relative to the mounting seat 11, and then adjust the height of the tensioning pulley 13 mounted on the sliding seat 12. Specifically, the lifting of the sliding seat 12 relative to the mounting seat 11 can be realized by the sliding block sliding rail mode, or by the transmission belt mode.

[0056] Since the tensioning pulley 13 is a metal part and has a certain weight, when the tensioning pulley 13 is arranged on the steel wire rope 2, it can provide a certain gravity to the steel wire rope 2 to drive the steel wire rope 2 to be tensioned downward.

[0057] At the same time, since the elastic member 14 arranged between the mounting seat 11 and the sliding seat 12 is in a compressed state during installation, the elastic force generated after the elastic member 14 is compressed generates a pushing force on the sliding seat 12, pushes the sliding seat 12 downward, and thus drives the tension pulley 13 to move downward, thereby pushing the steel wire rope 2 downward to tension.

[0058] In actual application, when installing the tensioning device 1, the mounting seat 11 is fixed on the lower cross beam of the stacker, the speed limiter is installed on the upper cross beam, one end of the steel wire rope 2 is wound around the speed limiter, and the other end is wound around the tension pulley 13 and then acts on the safety clamp. The length of the steel wire rope 2 is gradually adjusted, the tension pulley 13 is pulled, the tension pulley 13 drives the sliding seat 12 to move upward to compress the elastic member 14, so as to tension the steel wire rope 2.

[0059] The tensioning device 1 for the speed-limited steel wire rope of the stacker provided by the utility model, by arranging the mounting seat 11, the sliding seat 12, the tension pulley 13 and the elastic member 14, and rotatably installing the tension pulley 13 on the sliding seat 12, winding the steel wire rope 2 on the tension pulley 13, and clamping the elastic member 14 between the mounting seat 11 and the sliding seat 12, adjusting the height of the tension pulley 13 to make the elastic member 14 in a compressed state when installing the tension pulley 13 through the lifting movement of the sliding seat 12 relative to the mounting seat 11, so that the elastic member 14 is pressed downward to apply a force to the sliding seat 12 and transmit the force to the tension pulley 13, and under the action of the gravity of the tension pulley 13, the tension pulley 13 is simultaneously acted on by the elastic force and the gravity, so that the steel wire rope 2 is always in a tensioned state, compared with the previous counterweight device, it is easy to shake due to inertia when the stacker runs at high speed, or the elastic force of the elastic member 14 is easily damaged, which leads to the loosening or even falling off of the steel wire rope 2, or in order to increase the tensioning force, the volume and weight of the tensioning device 1 need to be increased, the tensioning device 1 of the utility model can be safely used in the scene where the lifting height of the stacker is large and the lifting speed is fast, the structure is compact and the space occupation is small, and it can also prevent swinging and realize automatic adjustment.

The positioning sleeve 16 can fill the gap between the spring and the adjusting rod 15, so that the inner wall of the spring has no radial movement space, preventing the spring from being eccentric during compression, and ensuring the stability and reliability of the spring compression.

[0082] The connecting plate 114 is connected with the second plate body 112 in a perpendicular manner, and the connecting plate 114 is arranged opposite to the sliding seat 12 to clamp the elastic member 14 between the connecting plate 114 and the sliding seat 12.

[0083] It can be understood that the first plate body 111 and the second plate body 112 of the embodiment are in a plate shape, the connecting seat 113 is a square tube, the first plate body 111 and the second plate body 112 are arranged on two sides of the connecting seat 113, and the first plate body 111 and the second plate body 112 are arranged in parallel.

Once the speed of the forks exceeds the preset value, the speed limiter triggers the locking action, drives the safety clamp to lock the steel wire rope 2 to prevent the movement of the steel wire rope 2, and then forces the forks to stop moving. The tensioning device 1 can provide constant tension for the steel wire rope 2, avoiding the relaxation of the steel wire rope 2 leading to the invalidation of the speed detection or the false triggering of the safety clamp.

[0092] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
