Description

Technical Field

[0001] This utility model relates to the field of mining lifting car technology, specifically a telescopic auxiliary platform for mining lifting cars. Background Technology

[0002] The telescopic auxiliary platform for mining lifting carriages is an auxiliary device specifically designed for mining operations. Its main function is to work in conjunction with mining lifting carriages to improve the efficiency and flexibility of cargo loading and unloading. The telescopic auxiliary platform adopts a multi-section telescopic structure design, which can adjust the length of the platform according to actual needs to adapt to the loading and unloading requirements of cargo of different sizes. The telescopic mechanism is usually driven by hydraulic or mechanical means.

[0003] For example, Chinese patent CN212890034U, entitled "A Safety Support Structure for Lifting a Mining Truck Cargo Box," includes a safety support rod, a vertical plate, a fixed seat, and a support. The vertical plate is fixed to the side of the vehicle frame, the fixed seat is fixed to the bottom of the cargo box, and the support is fixed to the side of the vehicle frame and located in front of the vertical plate. The bottom end of the safety support rod is hinged to the vertical plate. When the cargo box is not lifted, the rotating safety support rod contacts the support, and the safety support rod is fixed to the support by fasteners. When the cargo box is lifted, the rotating safety support rod cooperates with the fixed seat to support the cargo box. The vertical plate is connected to the vehicle frame through a fixing structure. The vertical plate is a U-shaped plate, and each of its two side plates has a corresponding pin hole, which cooperates with a shaft to restrict the movement of the safety support rod.

[0004] While the existing technologies mentioned above can enable the use of lifting carriages, in practical applications, the safety of the carriages is not good enough. Usually, the carriage doors need to be opened manually before unloading, which can cause the doors to pop open when the carriage is overloaded, increasing the risk of personnel being hit. On the other hand, there are certain blind spots in the carriage baffles. Usually, after the telescopic platform is extended, there is a certain gap in the baffle between the telescopic platform and the fixed platform, which makes it easy for goods to fall during transportation. Therefore, they do not meet the current requirements. In response, we propose a telescopic auxiliary platform for mining lifting carriages. Utility Model Content

[0005] The purpose of this utility model is to provide a telescopic auxiliary platform for mining lifting cars, so as to solve the problems mentioned in the background art, such as the insufficient safety of the car body and the existence of certain blind spots in the car body's baffles.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a telescopic auxiliary platform for a mining lifting car, comprising a base body, a fixed platform above the base body, telescopic cavities on both sides of the fixed platform, one side of the telescopic cavity being an open structure, a telescopic platform inside the telescopic cavity, the telescopic platform slidingly limiting the telescopic cavity, one end of the telescopic platform extending to the outside of the telescopic cavity, and grooves inside the front and rear ends of the upper end of the telescopic platform, two mounting seats fixedly mounted on one side of the telescopic platform on one side of the fixed platform, the mounting seats being symmetrically arranged, a fixed plate fixedly mounted on the upper end of the mounting seats, a fixed rod arranged between the fixed plates, the fixed rod being rotatably connected to the fixed plate, and a rotating plate fixedly mounted on the outside of the fixed rod.

[0007] Preferably, a drive motor is fixedly installed above the outside of the fixed rod, and the output shaft of the drive motor extends into the interior of the fixed plate and is fixedly connected to the fixed rod.

[0008] Preferably, an installation baffle is fixedly installed on one side of the telescopic platform located on the other side of the fixed platform. Slots are provided on both sides of the installation baffle and the inside of the fixed plate. The slots have an open structure. Insertion baffles are provided at the front and rear ends of the upper end of the telescopic platform. The lower end of the insertion baffle extends into the groove on the telescopic platform. A snap-fit ​​strip is fixedly installed on one side of the insertion baffle. The snap-fit ​​strip extends into the slot and snaps into the slot.

[0009] Preferably, the front and rear ends of the upper end of the fixed platform are fixedly provided with fixed baffles, and the fixed baffles are in contact with the plug-in baffles.

[0010] Preferably, both the lower part of the rotating plate and the interior of the mounting base are provided with through holes. The through holes are of a through-hole structure, and the positions of the through holes on the rotating plate and the mounting base correspond. A bolt is provided on the outside of the mounting base, and the rear end of the bolt extends to the outside of the mounting base through the through hole. A nut is sleeved on the outside of the bolt, and the nut contacts the mounting base.

[0011] Preferably, a first mounting ear plate is fixedly installed at each of the four corners of the lower end of the fixed platform, and a second mounting ear plate is fixedly installed at the front and rear ends of one side of the upper end of the base body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can electrically open the rotating plate by means of a drive motor and a fixed rod. When unloading, the bolts have been removed from the mounting base. At this time, the drive motor is turned on, so that the output shaft of the drive motor drives the fixed rod to rotate. At this time, the rotating plate, which is fixedly connected to the fixed rod, rotates together until an opening is formed between the telescopic platform and the rotating plate. At this time, the fixed platform and the telescopic platform are tilted by the first hydraulic telescopic device and the second hydraulic telescopic device. The goods are unloaded from the inside of the carriage through the opening between the telescopic platform and the rotating plate, thus ensuring the safety of the unloading process.

[0015] (2) This utility model can cover the telescopic platform by using a snap-fit ​​strip and a plug-in baffle. When the telescopic platform is unfolded, the plug-in baffle is aligned with the groove opening on the telescopic platform, and the snap-fit ​​strip is aligned with the slot. At this time, the plug-in baffle moves downward, so that the snap-fit ​​strip on the plug-in baffle enters the slot and slides downward until the snap-fit ​​strip moves to the appropriate position. At this time, the lower end of the plug-in baffle moves into the groove on the telescopic platform and contacts the fixed baffle on the fixed platform, thereby reducing the risk of goods falling during transportation.

[0016] (3) The rotating plate can be fixed by bolts and through holes. After the goods are loaded, the rotating plate is in a vertical position. At this time, the bolt is aligned with the through hole opening on the mounting base and inserted into the through hole until one end of the bolt passes through the through hole, penetrates the rotating plate and extends to the outside of the mounting base. Then, the nut is put on the outside of the bolt and rotated until the nut is rotated to the appropriate position. At this time, the nut contacts the side wall of the mounting base, thereby improving the safety of the rotating plate. Attached Figure Description
