Problems solved by technology

[0003] The existing "a lifting device for the video probe of the chute" (CN102992222A) controls the lifting of the video probe of the chute in the chute by manually shaking the handle to collect the video information of the wall of the chute. The device has the following disadvantages: 1. In use Need to build a working platform, the operation is cumbersome
2. The improvement of the video probe needs to be done manually, which is time-consuming and labor-intensive
3. The moving speed of the video probe cannot be adjusted, which affects the shooting quality of the probe

Embodiment 1

[0031] An automatic lifting device for a chute video probe. Such as figure 1 As shown, the automatic lifting device is composed of a support frame 1, a guiding system 2, a frame 3, a well depth positioning system 4, a lifting system 5 and a control system 6.

[0032] The structure of the support frame 1 is as figure 2 As shown: the two ends of the threaded steel pipe 7 are symmetrically installed on the upper end of the "A"-shaped leg 9 through threads, and the tile-shaped steel brackets 8 are symmetrically fixed near the two ends of the threaded steel pipe 7, and the two tile-shaped steel brackets The center line of 8 is perpendicular to the axis of threaded steel pipe 7 and is set horizontally.

[0033] The structure of guidance system 2 is as follows image 3 As shown: the middle of the two first longitudinal steel pipes 10 is symmetrically welded with the first horizontal steel pipe 17 on the left side, and the two first horizontal steel pipes 17 penetrate from the cor...

Embodiment 2

[0043] An automatic lifting device for a chute video probe. Except following technical parameter, all the other are with embodiment 1:

[0044] The length of the first transverse steel pipe 17 is 1 / 4 to 1 / 3 times the length of the second transverse steel pipe 12;

[0045] The distance between the two longitudinal beams 21 is 1.2 to 1.3 times the width of the reel 31 .

[0046] Compared with the prior art, this specific embodiment has the following positive effects:

[0047] 1. No need to build a working platform. When this specific embodiment is used for the detection of the chute shaft wall, the support frame 1 and the frame 3 are respectively placed on both sides of the chute unloading mouth, and the video probe 29 is suspended in the center of the chute through the guide system 2, without building a working platform. Both the support frame 1 and the guide system 2 can be disassembled, and the operation is simple and convenient.

[0048] 2. Save time and effort. In this...

Abstract

The invention relates to an automatic lifting device for a draw shaft video probe. According to the technical scheme, the left ends of first longitudinal steel pipes (10) are laid on tile-shaped steel brackets (8) of a support frame (1), the right ends of the first longitudinal steel pipes (10) are connected with second longitudinal steel pipes (19) through screwed connectors, and first vertical steel pipes (14) are connected with second vertical steel pipes (18) through screwed connectors; a hollow main shaft (32) is provided with a winding drum (31) and installed in a second bearing seat (33) through a bearing, and one end of the hollow main shaft (32) is connected with a variable-frequency motor (34) through a speed reducer (35); the video probe (29) is hung at the end of a flat cable (30), and the flat cable (30) is wound on the winding drum (31) of a lifting system (5) through a first guide wheel (11) and a second guide wheel (13) in a guide system (2) and a counting shaft (27) in a shaft depth positioning system (4). The automatic lifting device for the draw shaft video probe has the advantages that a working platform does not need to be set up, disassembly and assembly are convenient, manpower and the time are saved, and the lifting speed is adjustable.

Description

technical field [0001] The invention belongs to the technical field of chute hoisting devices. In particular, it relates to an automatic lifting device for a chute video probe. technical background [0002] The chute is an important channel for ore transportation, and the stability and smoothness of the chute is the prerequisite for the continuous and efficient production of the mine. Due to the frequent impact and wear of the ore, the shaft wall of the chute is easily deformed and damaged, which increases the risk of blockage of the chute. Once the chute is blocked, the operation of the mine will be paralyzed, so it is necessary to overhaul and reinforce the chute after the chute is emptied, so as to prepare for the next time the chute draws ore. Due to the particularity of the chute environment, maintenance personnel often need to go down into the chute to clean and reinforce the chute wall, which is a heavy workload, time-consuming and laborious, and there are hidden da...
