Description

Technical Field

[0001] This utility model relates to the field of brick manufacturing technology, and in particular to a multi-layer concrete brick transport vehicle. Background Technology

[0002] During the manufacturing process of concrete bricks, curing is required to enhance their hardening strength. In large-scale industrial production, concrete bricks are usually placed in multiple layers in a curing kiln to control temperature and humidity. Therefore, a transfer vehicle capable of transporting multiple layers of bricks at once is needed during the brick transfer process.

[0003] Chinese invention patent application CN103587908A discloses a mother-daughter car transport device for a brick-making production line. The transport device consists of a daughter car and a mother car. The mother car moves along the main track, which can drive the daughter car to the next set of daughter car tracks. After the daughter car tracks are connected to the next set of tracks, the daughter car and the mother car separate. The daughter car moves along the connected track, which can realize the placement of bricks and brick slabs on the insert arm into the curing room or the extraction and transportation from other production line mechanisms to the daughter car. This equipment improves productivity and reduces the labor intensity of operators. Its disadvantage is that if the daughter car separates due to inaccurate track connection, it will cause the daughter car to derail, affecting the safety of surrounding operators. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-layer concrete brick transfer vehicle, in which the transfer vehicle cannot be separated from the mother vehicle if the track of the transfer vehicle is not aligned, and the transfer mother vehicle has an emergency braking system that can brake suddenly in case of a possible collision.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-layer concrete brick transfer vehicle, including a transfer mother car and a transfer daughter car. The transfer mother car includes a mother car frame, a mother car power system is provided at the bottom of the mother car frame, an emergency braking system is provided on the forward side of the transfer mother car, an upper rail of the mother car that cooperates with the transfer daughter car is provided at the place where the transfer mother car is placed, a daughter car limiting mechanism is provided below the upper rail of the mother car, and the transfer daughter car includes a daughter car frame, a daughter car power system is provided below the daughter car frame, and a multi-layer forklift arm system is provided above the daughter car frame.

[0006] By adopting the above technical solutions, the transfer mother car can tow the transfer daughter car to move to the designated position on the ground track. The daughter car limit mechanism only allows the transfer daughter car to pass when the track on the mother car is aligned with the track on the ground. The multi-layer forklift arm system can lift and lower to take out and put in the finished bricks in the curing kiln. When the transfer mother car collides with the wall or the surrounding operators, it can be stopped quickly by the emergency braking system.

[0007] A further feature of this invention is that the mother car power system includes a pair of power wheels and a pair or more auxiliary wheels rotatably connected to the bottom of the mother car frame. Each power wheel includes a rotating part and a mother car drive mechanism that drives the rotating part to rotate. The mother car drive mechanism can change the rotation direction of the output shaft, and the power wheel can move along the ground track.

[0008] By adopting the above technical solution, the mother car drive mechanism drives the transfer mother car to move back and forth on the ground track. This technology is existing technology and can be referred to as the wheel drive method of electric vehicles.

[0009] A further feature of this invention is that the emergency braking system includes a pressure rod installed on the side wall of the mother car frame in the forward direction, one end of the pressure rod being rotatably connected to the mother car frame, a sensor for detecting the rotational position of the pressure rod being installed above the connection point of the pressure rod, and a brake pad for reducing the wheel speed being installed at the drive wheel.

[0010] By adopting the above technical solution, the pressure rod remains stationary when it is not under force. When the transfer mother car is hit, the pressure rod will rotate under force. The sensor detects the change in the position of the pressure rod and activates the brake pads to decelerate quickly. The method of deceleration by the brake pads can refer to the working principle of brake pads during vehicle operation.

[0011] A further feature of this invention is that the subcar limiting mechanism includes a subcar wheel limiting block that can move longitudinally between the tracks on the mother car, a pressure spring that is fixed to the bottom of the mother car frame and connected below the subcar wheel limiting block, a limiting plate that can move along the track direction on the mother car frame and a limiting groove that cooperates with the subcar wheel limiting block is provided on the limiting plate, and a limiting spring is provided on the side of the limiting plate along the direction of movement.

[0012] By adopting the above technical solution, when the mother car reaches the designated position, the limiting plate and the mating protrusion installed on the ground collide and squeeze until they retract into the mother car frame. At this time, the position of the limiting groove on the limiting plate changes, allowing the limiting hole to pass downward through the limiting groove until the wheels of the transfer car will not collide with the limiting block. At this time, the transfer car can drive out along the track on the mother car and separate from the mother car. The transfer car then arrives at the curing kiln.

[0013] A further feature of this invention is that the trolley power system includes a pair of trolley power wheels and a pair of trolley auxiliary wheels rotatably connected to the bottom of the trolley frame. Each trolley power wheel includes a trolley wheel rotating part and a trolley drive motor that drives the trolley wheel rotating part to rotate. The trolley drive motor can change the rotation direction of its output shaft. The wheel spacing between the trolley power wheels and the trolley auxiliary wheels is the same as the track spacing on the mother car.

[0014] A further feature of this invention is that the multi-layer forklift arm system includes a forklift arm base disposed above the sub-carriage frame, a forklift arm lifting frame disposed between the forklift arm base and the sub-carriage frame, and a multi-layer forklift chassis vertically fixed above the forklift arm base. The multi-layer forklift chassis is connected to several layers of longitudinally arranged transverse support rods.

[0015] By adopting the above technical solution, the forklift boom lift can longitudinally push the forklift boom base, changing the distance between the multi-layer forklift chassis and the ground, making it easier to remove concrete bricks.

[0016] A further feature of this invention is that the forklift boom lift includes a lifting base fixed on the truck frame and a lifting top plate fixed below the forklift boom base. Both sides of the lifting base and the lifting top plate are provided with transverse grooves. The forklift boom lift includes scissor lifting components arranged on both sides of the lifting base.

[0017] By adopting the above technical solution, the forklift boom lift adopts a scissor lifting structure, and its lateral bearing capacity is sufficient to support the weight of multi-layer forklift chassis and concrete bricks. The lifting base is provided with a hydraulic cylinder on the side opposite to the groove to drive the lifting of the scissor lifting assembly. This structure is easy to maintain and has a low cost.

[0018] A further feature of this invention is that the scissor lift assembly includes a first lifting rod and a second lifting rod that are centrally hinged to each other. The lower end of the first lifting rod is hinged to the side of the lifting base, and the upper end of the second lifting rod is hinged to the side of the lifting top plate. The upper end of the first lifting rod and the lower end of the second lifting rod cooperate with the groove.

[0019] A further feature of this invention is that the transfer trolley is also equipped with a counterweight mechanism, which includes a counterweight frame fixed to the rear side of the multi-layer forklift arm system, a longitudinal counterweight block fixing rod is provided inside the counterweight frame, and several counterweight blocks are detachably provided outside the counterweight block fixing rod.

[0020] By adopting the above technical solution, when the multi-layer forklift boom system is carrying a large amount of concrete bricks, the front mass of the transfer trolley is too large, the center of gravity is unstable and it is easy to tip over. Therefore, it is necessary to add a counterweight at the rear to maintain the balance of the trolley.

[0021] A further feature of this invention is that the transfer cart is also equipped with a winch for storing power cables.

[0022] By adopting the above technical solution, the transfer trolley is far from the transfer mother car when entering the curing kiln, requiring a long cable for power supply. When returning to the mother car, the excessively long cable needs to be collected by a winch and placed on the ground for dragging.

[0023] The beneficial effects of this utility model are:

[0024] 1. The subcar limiting mechanism prevents the transfer subcar from separating from the transfer subcar when the mother car's upper track and the ground track are not aligned, thus reducing the risk of derailment.

[0025] 2. The emergency braking system enables the transport vehicle to stop quickly in the event of an accidental collision, further reducing damage and casualties. Attached Figure Description
