Embodiment Construction
[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0021] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative relationship between the various components in a certain posture (as shown in the accompanying drawings). When the positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

The invention discloses a mechanical jacking device. The mechanical jacking device comprises a main rod, a bearing frame bearing a weight, a drive mechanism driving the bearing frame to move up and down along the main rod, and a self-locking mechanism which moves up and down along the main rod along with the bearing frame and is used for forming friction self-locking with the main rod. During use,the main rod forms main supporting, the heavy is borne on the bearing frame, and the drive mechanism can be driven through external force to work so as to drive the bearing frame to move upwards along the main rod; and due to the arranged self-locking mechanism, self-locking is formed by the self-locking mechanism every time the bearing frame moves upwards by a certain distance, the bearing frameis prevented from sliding downwards, and therefore jacking of the weight is completed. The mechanical jacking device can be achieved completely through a mechanical structure, no hydraulic or pneumatic system is needed, and the manufacturing and using cost is greatly reduced; meanwhile, the mechanical structure of the mechanical jacking device is simple and reasonable, and safety of jacking operation can be greatly improved through the self-locking function in the jacking process; and the size is relatively small, and the mechanical jacking device can be suitable for work conditions of jacking of different weights.
Description
technical field [0001] The invention relates to the technical field of lifting heavy objects, in particular to a mechanical jacking device. Background technique [0002] A jacking device refers to a device that uses a combination of hydraulic systems or mechanical components (such as screws, gears, transmission motors, etc.) to jack up objects or use objects to lift, such as jacks, jacking machines, cranes, etc. Among them, the jacking device using the oil pressure system has a simple structure and reliable jacking, but it needs hydraulic functions to realize it, and the cost is high, and it needs supporting equipment to maintain the normal realization of the hydraulic functions; while the existing mechanical components The structure of the jacking device that realizes the jacking function is generally relatively complicated, requiring a large bracket and gear transmission mechanism, and the manufacture and installation are relatively complicated, and the volume is generally...
