Description

Linear guide rail lifting mechanism

Technical Field

The utility model relates to the technical field of machinery and automation, in particular to a linear guide rail lifting mechanism.

Background

For example, in some equipment fields, such as inspection robots, it is desirable to perform inspection work on long-distance or complex sites, such as pipe lanes and coal mines, for site safety and effective guarantee of personal safety of inspection personnel. Because the inspection robot has basic characteristics of perception, decision, execution and the like, the inspection robot can assist or even replace human beings to finish dangerous, heavy and complex work of inspection, and the work efficiency and quality are improved.

When the inspection robot works, the track platform is usually used as a carrier to move on the track along a fixed running path, and the environment needing inspection is monitored. As technology advances and demand increases, rail inspection robots have also begun to be employed in many places, such as factories, farming plants, smart farms, municipal pipe galleries, underground coal mines, etc.

However, although the existing track inspection robot can freely run and adjust the position on the plane or the general plane along the track, the existing inspection robot cannot adjust the height of the inspection robot or cannot adjust the height of the inspection robot in a real-time, flexible and controllable manner, i.e. cannot control the lifting of the inspection robot so as to meet the requirements of the inspection height workplace and realize more flexible inspection.

There is a continuing need in the art for improved linear guide lift mechanisms to continue to improve inspection robot performance and to minimize or even eliminate the above-described technical drawbacks, as well as to achieve other, further technical advantages.

The information included in this background section of the specification of the present utility model, including any references cited herein and any descriptions or discussions thereof, is included solely for the purpose of technical reference and is not to be construed as a subject matter that would limit the scope of the present utility model.

And so on until the nth-1 linear slide rail-slide block module, wherein the slide rail 141 of the nth-1 linear slide rail-slide block module is provided with an nth-1 upper chain wheel on the opposite side of the end corresponding to the lower chain wheel of the nth-2 linear slide rail-slide block module, the same side of the other end of the slide rail 141 of the nth-1 linear slide rail-slide block module along the length direction is provided with an nth-1 lower chain wheel, the nth-1 upper chain wheel and the nth-1 lower chain wheel are provided with an nth-1 transmission chain 147, one end of the nth-1 transmission chain 147, which is close to the nth-1 upper chain wheel, is fixedly provided with a linked nth-1 upper linkage connecting piece 148, the nth-1 upper linkage connecting piece 148 is connected with the slide rail 141 of the nth-2 linear slide rail-slide block module, one end, which is close to the nth-1 lower chain wheel, of the nth-1 lower chain wheel is fixedly connected with the nth-1 linear slide rail-slide block module, the nth-1 linear slide rail-slide block module is driven by the linear slide rail 148, the nth-1 linear slide rail-1 is driven by the linear slide rail-1 upper chain-1, the nth-1 linear slide block module is driven to move, and the nth-1 linear slide block module is simultaneously, and the nth-1 linear slide block module is driven by the linear slide rail-1 is driven by the linear slide rail module, and the linear slide block module, and the nth-slide block module, n is more than or equal to 4.

In the case of n=1, the slide 143 of the 1 st linear rail-slide module may be fixedly connected to the lower platform to achieve the lifting operation.

According to one example, the motor 170 includes an operatively coupled worm gear reduction mechanism 171.

The position at which the slider 143 of the linear rail-slider module is fixedly connected to the rail 147 of the next linear rail-slider module is not particularly limited, and basically, the extended and retracted states of the lifting device according to the present utility model can be realized. However, as a preferred embodiment, in the fully extended state, the slide 143 of the 1 st linear rail-slide module is fixedly connected, e.g., face-to-face, with the substantially upper end position of the slide 141 of the 2 nd linear rail-slide module at the substantially lower end position of the 1 st linear rail-slide module, the slide 143 of the 2 nd linear rail-slide module is fixedly connected, e.g., face-to-face, with the substantially upper end position of the slide 141 of the 3 rd linear rail-slide module at the substantially lower end position of the 2 nd linear rail-slide module, and so on … until the slide 143 of the n-1 th linear rail-slide module is fixedly connected, e.g., face-to-face, with the substantially upper end position of the slide 141 of the n-1 th linear rail-slide module at the substantially lower end position of the n-1 th linear rail-slide module. This has the advantage that the extension length of each linear rail-slide module can be utilized to a maximum extent and with maximum efficiency.

As shown, the lifting device 100 may further include a retractable power cable 150, for which purpose the lifting device 100 may further mount a winch 130 on one of the linear rail-slide modules of the linear rail lifting mechanism 140, for example, on one of the sprockets in the middle portion (e.g., one of the sprockets 147B on the right side of fig. 5-6), as shown in fig. 5 and 8. The winch 130 is configured to wind and unwind the power supply cable 150 in linkage with the lifting movement of the lifting device 100 to achieve the linkage stowing and unwinding of the power supply cable 150, thereby facilitating the tidy and safe and reliable wiring of the power supply cable 150, avoiding the winding from causing a malfunction, and saving space.

According to an example, the linear rail-slider module may have balls built therein to facilitate smoother and reliable sliding of the rails 141 and the sliders 143 of the linear rail-slider module relative to each other.

According to an example, the lift device 100 may be provided with an opto-electronic travel switch configured to send a travel end signal after the lift device is fully retracted.

According to an example, in the stowed state of the lifting device 100, the 1 st to nth linear rail-slider modules are stacked face-to-face side-by-side with one another, as shown in fig. 2.

According to an example, all linear rail-slider modules have the same length, which facilitates a more orderly and space-saving stacked condition after stowing. Of course, different linear rail-slider modules may have different lengths.

As shown in fig. 2 and 4, the nth, i.e., the lowermost, linear rail-slide module, which may be provided with the reinforcement/mounting members 146, is secured to the lower platform 120 by means of the support 160, and the inspection robot module 300 may also be secured to the lower platform 120, e.g., the bottom surface thereof. The support 160 may be in the form of a stiffener/baffle 160 on each side of the linear rail-slide module so that the support 160 not only serves to assist in mounting and strengthening the structural strength, but the support 160, lower platform 120 and the nth linear rail-slide module together form a "dock" like seat for receiving the linear rail lift mechanism 140, serving as a linear rail-slide module that helps to retain and receive the collapsed linear rail lift mechanism 140 in the stowed condition.

The lifting operation of the lifting device 100 according to one example is further described below. Generally, the lifting device 100 is configured to be bi-directionally driveable: (1) In a stow operation step, the 2 nd to nth linear slide-and-slide modules are configured to be rotated by the motor 170 in one direction (e.g., clockwise) from a partially or fully extended state of the lift device 100 to substantially simultaneously rotate the 1 st drive chain 147 and the remaining full drive chain (including rotation of the chain about the sprocket and linear movement of the chain in the linear section) and the stow movement of the associated 2 nd to nth linear slide-and-slide modules in the linear elevation direction, and eventually to be stacked in a face-to-face side-by-side manner, for example, with each linear slide-and-slide module until fully stowed, as shown in fig. 2-3; and (2) extending, during the extending step, the 2 nd to nth linear slide-and-slide modules are configured to be rotated in opposite directions (e.g., counterclockwise) from a partially or fully stowed condition of the lift device 100 by the motor 170 to drive the 1 st drive chain 147 in opposite directions to substantially simultaneously drive the remaining entire drive chain in reverse rotation (including reverse rotation of the drive chain about the sprocket and reverse linear movement of the chain in the linear section) and the associated extending movement of the 2 nd to nth linear slide-and-slide modules in the linear lowering direction, ultimately extending in the 2 nd to nth linear slide-and-slide modules to the fully extended condition, as shown in fig. 5.

According to one example, a motor may be required to provide a braking force to ensure that the lift 100 stops and stays at a desired extended height. Preferably, therefore, the motor 170 is preferably self-contained with a braking mechanism (e.g., a self-locking worm gear reduction mechanism 171, without the need for an additional braking device) so that it can remain stationary in any desired partially extended condition by the motor braking mechanism.

According to one example, the motor may be of any suitable type, such as a stepper motor, but this example is not intended to be limiting. In general, it is preferable that the motor is arranged so that the lifting speed of the lifting device 100 is 20 cm/sec or more, for example 50 cm/sec or more.
