Description

TECHNICAL FIELD

[0001] The application relates to the technical field of mine transportation, in particular to a mine conveying trolley with a speed reduction function. BACKGROUND

[0002] The mine conveying trolley is a key equipment in a mine transportation system and is mainly used for transporting heavy loads in underground or open-pit mines. Due to the particularity of the mine environment, such as complex terrain, uneven tracks and variable working conditions, the safety and reliability of the conveying trolley are highly required. The traditional mine conveying trolley mainly relies on mechanical transmission and manual operation to control the speed, which is not only low in efficiency but also slow in response speed in emergency situations, and cannot effectively control the speed of the trolley in time. In addition, these methods often rely on electric drive, and in the case of power failure or control system failure, the trolley may lose control, increasing the risk of accidents. At the same time, direct contact between metal parts can easily cause wear and tear of the track and the equipment itself, increasing maintenance costs and time, and posing a great safety hazard.

Based on the embodiments in the present application (for the convenience of description and understanding, the following embodiments are described with reference to the drawings), all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of the present application.

[0018] Please refer to Figures 1-4 The present application provides a technical solution: a mine conveying trolley with a deceleration function, comprising a vehicle body 1, a guide wheel set is arranged around the lower surface of the vehicle body 1.

[0019] The vehicle body 1 is the structural core of the mine conveying trolley, bearing the load of the transported material, and has strong stability and reliability; the vehicle body 1 contains a elastic structure to absorb vibration and improve running stability, and the guide wheel set is fixed around the lower surface of the vehicle body 1, which rolls on the track to make the trolley smoothly advance or retreat.

[0020] The lower surface of the vehicle body 1 is also provided with a chassis plate on both sides, and the chassis plate is provided with a deceleration assembly 6.

[0021] When the speed of the trolley is detected to exceed the preset safety threshold, the deceleration assembly 6 can quickly respond and start the deceleration program to ensure that the trolley runs at a safe speed, automatically adjusts the deceleration degree according to the data of the speed sensor 3, without manual intervention, improves the convenience and safety of operation, and slows down the speed of the trolley through the friction between the clamping block and the track; this mechanical deceleration method can ensure basic safety deceleration function even in the case of power failure.

[0022] The deceleration assembly 6 comprises an intermediate connecting seat 10, a side frame plate 11, an adapter seat 12, a connecting clamping frame 13, an upper support plate 14 and a driving group, the two sides of the intermediate connecting seat 10 are provided with the side frame plates 11, the side frame plates 11 are provided with guide grooves, the two sides of the guide grooves are provided with the adapter seats 12, the intermediate connecting clamping frame 13 is hinged to the adapter seats 12, the end of the connecting clamping frame 13 is provided with a clamping block, and the other end of the connecting clamping frame 13 is provided with the upper support plate 14 on the upper surface.

[0023] The side frame plates 11 on both sides are fixed together through the middle connecting seat 10, ensuring the structural stability and strength of the deceleration assembly 6 as a whole, the ability of the middle connecting seat 10 to withstand high load and vibration, and long-term reliable operation in harsh environments such as mines; the side frame plates 11 provide mounting positions for the adapter seat 12, the connecting clamping frame 13 and related components; the side frame plates 11 are provided with guide grooves, allowing the connecting clamping frame 13 to rotate in the guide grooves of the side frame plates 11 with the adapter seat 12 as the center line, thereby accurately controlling the angle of the connecting clamping frame 13; the middle of the adapter seat 12 is hinged to the connecting clamping frame 13, allowing the latter to rotate around the hinge shaft to apply pressure to the track when needed; the connecting clamping frame 13 is provided with clamping blocks at one end, which tightly adhere to the surface of the track to slow down the trolley through friction when deceleration is needed; the other end is connected to the upper support plate 14, forming a stable mechanical structure to ensure the reliability of the clamping action; the connecting clamping frame 13 can be flexibly adjusted in angle through the hinge of the adapter seat 12 to adapt to the deceleration needs in different situations; the upper support plate 14 provides a stable mounting position for the drive group, ensuring that the related drive elements can work reliably.

[0024] The upper surface of the upper support plate 14 is provided with a drive seat connected to the side frame plate 11.

[0025] Further, one side of the trolley frame body 1 is provided with a speed detection group, which includes a right-angle support plate 4 and a speed sensor 3, and the speed sensor 3 is arranged on the right-angle support plate 4.

[0026] The speed detection group is responsible for real-time monitoring of the speed of the trolley, which is composed of a right-angle support plate 4 and a speed sensor 3.

[0027] The right-angle support plate 4 is the mounting base of the speed sensor 3, which provides stable support for the speed sensor 3, and the speed sensor 3 is used to measure the speed of the trolley in real time. The speed sensor 3 can be implemented in multiple technologies, such as optical encoder or magnetic encoder, etc., which provides accurate speed data by sensing the change of trolley movement.

[0028] Further, the trolley frame body 1 is also provided with a control module 2.

[0029] Further, the drive seat includes an oil cylinder mounting plate 8, a locking guide shaft 9 and a pressing oil cylinder 15, the pressing oil cylinder 15 is arranged on one side of the oil cylinder mounting plate 8, and the oil cylinder mounting plate 8 is arranged on one side of the side frame plate 11 through the locking guide shaft 9.

[0030] The oil cylinder mounting plate 8 provides a stable mounting position for the pressing oil cylinder 15, ensuring that the pressing oil cylinder 15 can exert or release sufficient pressure when working; through the locking guide shaft 9, the oil cylinder mounting plate 8 is fixed on one side of the side frame plate 11, ensuring the stability of the oil cylinder working.

[0031] Further, the guide wheel set comprises a guide wheel mounting frame 5 and a movable guide wheel 7, the movable guide wheel 7 is arranged on the guide wheel mounting frame 5.

[0032] Further, the inner side wall of the clamping block is provided with a friction deceleration slide.

[0033] The friction deceleration slide is made of a material with high friction coefficient, such as rubber, ceramic or special composite material, which can provide greater friction between the clamping block and the track, thereby more effectively slowing down the trolley. Compared with direct metal contact, the friction deceleration slide can reduce the wear on the track surface and protect the track from excessive damage.

[0034] Further, the connecting clamping frame 13 is provided with a through hole, and the through hole of the connecting clamping frame 13 is coaxially arranged with the through hole of the adapter seat 12.

[0035] In use: confirm that the speed sensor 3 on the right-angle support plate 4 is correctly installed and calibrated to ensure that it can provide accurate speed data; when the mine conveying trolley starts to run along the track, the speed sensor 3 immediately enters the monitoring state and continuously tracks the speed change of the trolley. The control system evaluates whether the current speed is within the preset safe range according to the real-time data provided by the speed sensor 3. If the speed is normal, the existing state is maintained to continue running; if overspeed is detected, the system will respond quickly. The control module 2 sends instructions to the compression cylinder 15 to push the connecting clamping frame 13 to close, and the connecting clamping frame 3 drives the clamping block and the internal friction deceleration slide to tightly adhere to the track surface, slowing down the trolley through the generated friction. With the action of friction, the trolley gradually slows down until it returns to the safe speed range. In this process, the control module 2 continuously adjusts the pressure of the compression cylinder 15 to ensure that the deceleration process proceeds smoothly. Once the speed returns to the set safe threshold, the control module 2 releases the pressure of the compression cylinder 15, and the connecting clamping frame 13 opens to restore normal running of the trolley.

[0036] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
