Description

Multi-stage lifting mine monkey car

technical field

The utility model relates to a monkey car for mines, in particular to a multi-stage lifting monkey car for mines.

Background technique

According to statistics, the mining depth of my country's coal mines increases at a rate of 8-12m per year. With the continuous increase of coal mine mining depth, a series of problems affecting coal mine production, such as the increase of rock formation pressure, significant deformation of roadway surrounding rock, and accelerated convergence and deformation of surrounding rock, are also becoming more and more serious. The practice of deep mining at home and abroad shows that when the mining depth is 800-1000m, the deformation of the roadway can reach 1000-1500mm, or even greater. The deformation of the roadway will block the underground traffic, damage the production equipment, cause casualties, and seriously threaten the safe production of coal mines.

As a cableway vehicle commonly used in mines and mines, monkey cars are mainly installed in inclined shafts and roadways up and down the mountain, so they are required to have higher safety. At present, the monkey cars used in mines all use fixed-height hanging chairs. With the deformation of the roadway, the normal operation of the monkey cars will inevitably be affected. If the monkey cars are replaced frequently, it will cause waste of resources and inconvenience management, and increase the production input of the coal mine. Based on the above actual situation, the design of a multi-stage lifting monkey car for mining can solve a series of problems caused by the deformation of the roadway, which is of great significance for ensuring the safety of coal mine production.

Contents of the invention

The purpose of this utility model is to provide a multi-stage lifting monkey car for mining. The user can adjust the height of the monkey car according to the actual needs of the mine, solve the problem of frequent replacement of the monkey car due to roadway deformation in the actual production process of the coal mine, and reduce the number of monkey cars with different specifications. Increase the vehicle inventory and improve the economic benefits of coal mines.

In order to achieve the above object, the utility model adopts the following technical solutions.

The monkey car mainly includes a rope gripper device suspended and connected with a power rope, a fixed boom with holes, and a seat rod; the fixed boom with holes and the rope grip device are flexibly connected through a fixed shaft; Both the fixed suspender and the seat post are provided with a certain number of perforations, the perforation spacing is 5cm, the inner diameter of the fixed suspender with holes is slightly larger than the outer diameter of the seat post, the fixed suspender with holes is nested and connected with the seat post, and is used to pass through the fixed perforations The two sets of fastening bolts are connected and fixed; the length of the fixed suspender with holes and the seat rod can be selected.

In the above technical solution, it is characterized in that the fixed suspension rod with holes is movably connected with the cable grip device through the fixed shaft, the monkey car naturally sags under the action of gravity, and the center of gravity is concentrated under the cable, so as to ensure that the seat rod and the fixed hanger with holes The force on the connecting part of the rod is evenly distributed on the two sets of fastening bolts; the seat rod is nested inside the fixed boom with holes, and the monkey car is set by adjusting the nesting position of the seat rod and the fixed boom with holes. The height is connected and fixed with two sets of fastening bolts through the fixed perforation to realize the stability of the connection between the seat rod and the fixed boom with holes; the fixed boom with holes and the seat rod with holes of different length specifications can be selected according to the actual situation of the coal mine roadway.

Beneficial effects of the utility model: the utility model multi-stage lifting mining monkey car can be fixed by selecting different lengths of the holed boom and the chair seat rod, and by adjusting the nesting position of the chair seat rod and the holed fixed boom The height of the monkey car solves the problem of frequent replacement of the monkey car lifting chair due to the deformation of the roadway in the actual production process of the coal mine, reduces the inventory of different specifications of the monkey car, and improves the economic benefits of the coal mine.

The utility model has a simple structure of the multi-stage lifting mine monkey car, and can quickly adjust the height of the monkey car at the place of use in the mine. It can be fixed with fastening bolts, which is convenient and practical.

Detailed ways

As shown in Figure 1, a multi-stage lift-type mining monkey car, the fixed suspension rod 2 with holes is movably connected with the cable grip device 1 through a fixed shaft, the fixed suspension rod 2 with holes is nested and connected with the seat rod 5, And connect and fix with two groups of fixing bolts 3 passing through the fixing holes 7. The monkey car sags naturally under the action of gravity, and the center of gravity is concentrated under the cable, ensuring that the force on the connection between the seat post 5 and the fixed suspender 2 with holes is evenly distributed on the two sets of fastening bolts 3; the seat post 5 is fixed with the holes Suspender 2 adopts nesting connection, and connects and fixes with two sets of fastening bolts 3, guarantees the stability that chair seat bar 5 is connected with fixed suspender 2 with holes.

In the practical application of the utility model multi-stage lifting monkey car for mining, according to the conditions of the mine roadway, different lengths of holed fixed suspenders and chair seat rods can be selected, and the height of the monkey car can be quickly adjusted at the place of use. When adjusting the height, only need to change the nesting position of the seat bar 5 and the fixed suspender 2 with holes, and fix it with the fastening bolt 3, which is convenient and practical.

The multi-stage lifting monkey car for mining of the utility model, the fixed suspender 2 with holes and the seat rod 5 can be disassembled and replaced, so as to meet the specifications of the monkey car in different roadway production environments and reduce production investment.
