Description

Technical Field

[0001] This utility model relates to the field of general downhole equipment, and in particular to a vehicle-stopping component. Background Technology

[0002] The safe operation of underground mine cars requires the installation of car-stopping mechanisms at their operating nodes, including locations such as the entire slope and loading / unloading points. Existing car-stopping mechanisms are diverse, and can be broadly classified into manually operated lever or sleeper types, as well as electrically controlled reversing types based on signal linkage, according to their operation methods.

[0003] In underground procurement, the same specifications of vehicle-stopping mechanisms are often used. However, due to different application scenarios, vehicle-stopping mechanisms at loading and unloading positions often do not involve slope changes and have lower requirements for response speed. On the other hand, tilting vehicle-stopping mechanisms have high procurement costs and involve multiple transmission components, resulting in higher maintenance frequency and difficulties in maintenance after impact. Currently, there is no corresponding solution to these problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a vehicle blocking component with a simpler structure, which ensures vehicle blocking strength, is extremely convenient to maintain, and is more suitable for use in non-slope locations.

[0005] The equipment includes a hydraulic cylinder, the piston portion of which is connected to an assembly shaft via a coupling;

[0006] I-shaped rails and anti-car blocks are spaced apart on the assembly shaft; the I-shaped rails and anti-car blocks are of equal width and parallel in direction.

[0007] The assembly shaft is movably set within the slotted section of the mine car running track, and the width of the I-shaped track and the car-stopping block is smaller than that of the slotted section of the mine car running track.

[0008] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 1 and Figure 2 As shown, under normal commuting conditions, the I-shaped track is placed within the slotted section of the mine car's running track, and the vehicle performs normal commuting functions. After the vehicle passes through the slotted section, the piston of the hydraulic cylinder moves the car-stopping block into the slotted section to achieve the car-stopping function.

[0009] The beneficial effects of this utility model are: this utility model provides a new type of vehicle blocking mechanism, which is especially suitable for vehicle blocking in underground non-slope positions; its structure is simpler, its manufacturing and maintenance costs are lower, and its service life and maintenance cycle are longer.

[0017] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] Reference Figure 1 , Figure 2 The present invention provides a vehicle-stopping component, which includes a hydraulic cylinder 1, wherein the piston portion of the hydraulic cylinder 1 is connected to an assembly shaft via a coupling.

[0019] I-shaped rails 2 and anti-car blocks 3 are spaced apart on the assembly shaft; the I-shaped rails 2 and anti-car blocks 3 are of equal width and are arranged in parallel directions.

[0020] The assembly shaft is movably set within the slotted section 4 of the mine car running track, and the width of the I-shaped track 2 and the car-stopping block 3 is smaller than that of the slotted section 4 of the mine car running track.

[0021] Preferably, "less than" here means slightly less than.

[0022] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 1 and Figure 2 As shown, under normal commuting conditions, the I-shaped track 2 is placed within the slotted section 4 of the mine car running track, and the vehicle performs normal commuting function; after the vehicle passes through the slotted section 4, the piston action of the hydraulic cylinder 1 causes the car-stopping block 3 to move into the slotted section 4, thereby achieving the car-stopping function.

[0023] Example 1, refer to the accompanying drawings in the specification. Figure 1 and Figure 2The hydraulic cylinder 1 is arranged on one side, and the I-shaped track 2 and the anti-car block 3 are arranged in two sets at intervals on the assembly shaft.

[0024] The effect achieved is to control the blocking and normal passage of the double rails in the mine car track by using a single hydraulic cylinder 1.

[0025] Example 2, refer to the accompanying drawings in the specification. Figure 4 There are a total of two hydraulic cylinders 1. The I-shaped rail 2 and the anti-car block 3 are respectively set on the assembly shaft connected to the two hydraulic cylinders 1. The two hydraulic cylinders 1 are axially symmetrical and are synchronously controlled by a reversing valve.

[0026] This achieves the effect of ensuring synchronized response of the two assembly shafts based on the synchronous drive control of the dual hydraulic cylinders 1. Furthermore, even if a single hydraulic cylinder 1 fails, it can still unidirectionally stop the vehicle, maintaining a basic stopping function, providing time for maintenance and improving operational safety.

[0027] In Example 3, a smooth support base is provided under the hardened construction of the slit section 4, and a sliding support part is integrally connected to the underside of the I-shaped track 2 and the vehicle blocking block 3.

[0028] Furthermore, the sliding support part adopts a support block, ball bearing or roller with a smooth bottom surface.

[0029] The effect achieved by this is that, with the support of the sliding support, the connection between the assembly shaft and the I-beam track 2 and the anti-roll block 3 has a lower risk of deformation, resulting in a longer service life and maintenance cycle. In other words, this equipment only requires maintenance when the assembly shaft deforms, and the maintenance only involves straightening the assembly shaft. The sliding support design minimizes the risk of equipment deformation.

[0030] In Example 4, the width of the slit section 4 is no more than 5cm, and the I-shaped track 2 is fitted with the slit section 4 with a clearance; the car blocking block 3 includes a base assembly block 31 set at the bottom, with a width of no more than 5cm and a height flush with the height of the mine car running track, and a stop block 32 integrally set on the base assembly block 31, with a width greater than that set on the base assembly block 31.

[0031] Furthermore, the stop block 32 is a tiered structure, including at least one inclined slope.

[0032] The effect achieved is to control the slit width while ensuring safe operation, thereby guaranteeing the strength and stability of track operation.
