Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and more particularly to a construction cargo transport elevator suitable for a trolley. Background Art

[0002] An elevator is a permanent transportation device that serves specific floors within a building, with its car running on at least two rows of rigid rails perpendicular to the horizontal plane or inclined at an angle of less than fifteen degrees to the plumb line. There are also stepped types, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways. It is a fixed lifting device that serves specific floors. Vertical elevators have a car that runs between at least two rows of rigid guide rails that are perpendicular or inclined at an angle of less than fifteen degrees. The size and structure of the car facilitate passenger entry and exit and loading and unloading of goods. Conventionally, elevators are used as a general term for vertical transportation vehicles within buildings, regardless of their driving method. Temporary elevators are often found on construction sites to improve the convenience of transporting goods between floors.

[0003] Among them, the patent with announcement number CN115838105A discloses a construction cargo transport elevator suitable for trolleys, which relates to the field of elevator technology. This construction cargo transport elevator suitable for trolleys includes a car mechanism, which includes a base, a fence fixedly connected to the outer side of the upper surface of the base, a car fixedly connected to the upper end face of the fence, a securing hole penetrating through the lower side of the rear wall of the car, the number of securing holes is three, a bottom plate fixedly connected to the inner side wall of the lower port of the car, a base hole penetrating through the middle of the surface of the bottom plate, and six extension slots penetrating through the front and rear inner walls of the base hole, the three extension slots on the rear side facing the three securing holes, and a delivery block provided inside the three extension slots on the front side, the cross section of the delivery block presenting a quarter circle and adapted to the extension slot; When this structure is in use, when the base rotates, the bottom block squeezes the airbag inside the bottom frame, so that the gas inside the airbag is transmitted to the inside of the cylinder through the air valve pipe and the air pipe. When the worker leaves the elevator, the slide loses its engagement. At this time, under the action of the inflation of the cylinder, the slide is pushed to move toward the elevator door, thereby driving the trolley out of the elevator. However, when this structure is in use, an individual and a trolley must enter the elevator at the same time, which requires the worker to follow the elevator up and down. Since the elevators at construction sites are usually temporary, this poses a great safety hazard. At the same time, it is impossible to achieve continuous and high-frequency transportation of trolleys, resulting in low construction efficiency. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a construction cargo transport elevator suitable for a trolley, aiming to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a construction cargo transport elevator suitable for a trolley, comprising a support base, on which two sets of positioning and conveying components are provided.

[0006] The positioning and conveying assembly includes a first rotating shaft arranged on one side of the support base, a second rotating shaft rotatably connected to the support base is arranged above the first rotating shaft, and both ends of the first rotating shaft and the second rotating shaft are sleeved with a conveyor belt; A plurality of supporting plates are provided on the outer sides of the two conveyor belts, and a plurality of supporting wheels for lifting the trolley are provided on one side of the plurality of supporting plates.

[0007] A sliding frame is provided at the bottom of the supporting wheel, and the sliding frame is installed on one side of the supporting plate and is slidably connected to the supporting plate. The sliding frame is provided with a number of support blocks with adjustable positions, and each of the support blocks is provided with a push rod, and one end of the plurality of push rods is provided with an air bag, and one end of each of the air bags is provided with a spring, and the spring is detachably connected to the air bag. Two pulleys are fixedly provided on the outer sides of the first rotating shaft and the second rotating shaft, and each of the pulleys is respectively located at the two ends of the corresponding conveyor belt inner cavity and is connected to the conveyor belt transmission. Two electric slide rails are provided on the top of the supporting base, and sliders are slidably connected to the two electric slide rails, and a first driving motor for driving the first rotating shaft to rotate is provided on one of the sliders.

[0008] It can be seen that in the above technical solution, the electric slide rail drives the slider to drive the first driving motor to move, and then the two positioning conveying components can be adjusted in position to achieve the function of adjusting the distance between the two, which makes it easy for the baffles belonging to each positioning conveying component to contact the side of the trolley to clamp the trolley. At the same time, the supporting wheel can extend to the bottom of the trolley to lift the trolley, which is convenient for the trolley to push and pull, and rub against the supporting wheel to facilitate its transportation. After the first driving motor is started to drive the first rotating shaft and the pulley to rotate, the pulley rubs against the conveyor belt when rotating, and then each support plate can be rotated by the traction force when the conveyor belt rotates, and the support plate is lifted, thereby achieving the function of lifting the trolley; Optionally, in a possible embodiment, the bottoms of the plurality of support blocks are rotatably connected to the folding frame by an axle pin, and a traction plate is provided on one side of one of the support blocks, and the traction plate and the support block are detachably connected by bolts, and the slide frame is mounted on a second driving motor through bolts, and an output end of the second driving motor is mounted on a screw rod, one end of the screw rod passes through the traction plate and extends to one side of the inner wall of the slide frame and is rotatably connected to the slide frame, and the traction plate is threadedly connected to the screw rod, and both sides of the support block and the traction plate are slidably connected to a guide rod, and each guide rod is mounted on the slide frame and detachably connected to the slide frame by bolts, and a baffle for blocking the trolley is provided on the support plate, and a support shaft is provided on one side of the support wheel, and the support shaft extends to the support plate and is rotatably connected to the support plate, and the end of the support plate is rotatably connected to a knob, and the knob is threadedly connected to a pull plate mounted on the end of the slide frame.

[0009] It can be seen that in the above technical solution, in order to ensure the stability of the trolley during transportation, the second driving motor is used to start the driving screw to rotate. When the screw rotates, the traction plate is driven to adjust its position on the slide frame along the guide of the guide rod, and then the traction plate pulls the folding frame to extend and unfold, so that each support block can be adjusted in position at the same time, which is convenient for the support block to contact different positions of the trolley. The spring and the airbag are deformed under the force and the elasticity of the spring and the airbag drives the airbag and spring to reset and contact the outside of the trolley, ensuring the stability of the trolley during transportation. At the same time, by rotating the knob, the pull plate drives the slide frame to slide on the support plate, so that the slide frame and the airbag can be moved to the bottom of the trolley to move the trolley, so that the trolley loses its limit and is easy to pull the trolley out from the supporting wheel.

[0010] Technical effects and advantages of the present invention: 1. The present invention drives the first drive motor to move by an electric slide rail, thereby enabling the two positioning and conveying components to be adjusted in position, thereby achieving the function of adjusting the distance between the two. It is easy for the baffles belonging to each positioning and conveying component to contact the side of the trolley to clamp the trolley. At the same time, the supporting wheels can extend to the bottom of the trolley to lift the trolley, making it convenient for the trolley to rub against the supporting wheels when being pushed or pulled, thereby facilitating its transportation. 2. The present invention starts the first drive motor to drive the first rotating shaft and the pulley to rotate. When the pulley rotates, it rubs against the conveyor belt, and then each pallet can rotate under the traction force of the conveyor belt, thereby lifting the pallet and realizing the function of lifting the trolley; 3. The traction plate of the present invention pulls the folding frame to extend and unfold, so that the positions of the various support blocks can be adjusted simultaneously, making it convenient for the support blocks to contact different positions of the trolley. The spring and the airbag are deformed under force and driven by their own elasticity to return to the original position and contact the outside of the trolley, ensuring the stability of the trolley during transportation. 4. The present invention rotates the knob to make the pull plate drive the slide frame to slide on the supporting plate, so that the slide frame and the airbag can be moved to the bottom of the trolley to move the trolley, so that the trolley is no longer limited, and it is easy to pull the trolley out from the supporting wheel. In addition, the conveyor belt rotates to drive the supporting plate to move to achieve the function of lifting the trolley. There is no need for workers to enter the device, and it is easy to realize the high-frequency transportation function of the trolley, thereby improving construction efficiency. The trolley is lifted up by the support plate, and the trolley is lifted up by the support plate, so that the trolley can be lifted up and the support plate can be lifted up.
