Description
Technical Field
[0001] The utility model relates to the technical field of construction machinery, in particular to a novel buffer base for a cargo construction hoist. Background Art
[0002] Freight hoists are essential vertical transportation equipment in high-rise building construction. Traditionally, the foundation of a construction hoist is installed on backfill soil or the basement roof. However, when the foundation is located above the basement floor, additional reinforcement is often required due to the limited bearing capacity of the basement roof. This not only increases construction steps and costs, but also, in actual operation, if the hoist stalls and falls, the lack of effective buffering devices can easily cause damage to the equipment or even the building roof.
[0003] Patent application number CN202121185509.X discloses a support chassis for a construction elevator, which relates to the field of construction equipment. The chassis includes a shock-absorbing base and a shell. Secondary support rods are fixedly connected to the left and right sides of the lower side of the shock-absorbing base, and a support plate is fixedly connected to the middle part of the lower side of the shock-absorbing base. Support legs are installed on the left and right sides of the lower interior of the shell, and the shell is located below the shock-absorbing base. The utility model uses secondary support rods, springs, main support rods, load-bearing plates, connecting rods, slides, and sliders to ensure that when the chassis is in use, when the load-bearing plates are subjected to vibration and gravity, the vibration and gravity are output to the sliders through the connecting rods, so that the sliders move inside the slides under the action of the connecting rods. The seismic resistance of the chassis can be increased by the sliders sliding inside the slides, so that the vibration generated by the elevator is reduced before it is transmitted to the chassis, preventing the chassis from being damaged by vibration during use and increasing the service life of the chassis and the elevator.
[0004] However, the aforementioned patented technology suffers from insufficient foundation bearing capacity and is prone to sinking. The foundation, located above the basement ceiling, requires calculations and reinforcement, a complex and costly process. Currently, some projects place the foundation on the basement floor, reserve a hole above the basement ceiling, pass the standard section through the reserved hole, and then install the entire machine. To address these issues, the market urgently needs a new base device that can provide both stable support above the basement ceiling and effective cushioning in the event of a lift stall. Utility Model Content
[0005] The purpose of this utility model is to provide a new type of buffer base for cargo construction hoist to solve the problems raised in the above background technology:
[0006] (1) How to solve the problem that some cargo construction elevators installed above the basement floor cannot be installed with buffer springs, and implement safety protection for the cargo construction elevators and the main structure of the building.
[0007] To achieve the above objectives, the present invention provides the following technical solutions:
[0008] A new type of cushioned base for cargo construction hoists;
[0009] The invention comprises two first support rods and two second support rods, the two first support rods and the two second support rods are arranged opposite to each other, and the two first support rods and the two second support rods are connected at their ends to form a rectangular frame, which is mounted on the outside of the standard section of the cargo construction elevator, and is placed at the edge of the reserved hole on the basement roof;
[0010] Several first buffer components are provided on the first support rod, and the first buffer component includes a first positioning tube and a first base plate. One end of the first base plate is fixedly connected to the side wall of the first support rod, and the other end of the first base plate extends to the outside of the first support rod. The lower end of the first positioning tube is fixedly connected to the first base plate, and the buffer spring is placed in the first positioning tube. The upper end of the buffer spring extends out of the upper side of the first positioning tube, and the first buffer component is located outside the rectangular frame.
[0011] On the basis of the above technical solution, the present invention can also be improved as follows.
[0012] Furthermore, the first support rod and the second support rod are detachably connected via bolts.
[0013] Furthermore, it also includes two groups of vertical extension rods, which correspond one-to-one to the two first support rods. Each group of vertical extension rods includes two vertical extension rods, and the vertical extension rods are fixedly connected to the side walls of the corresponding first support rods. The vertical extension rods are located on the inner side of the rectangular frame, and the distance between the two vertical extension rods in the same group corresponds to the width of the standard section of the cargo construction elevator.
[0014] Furthermore, the vertical extension rod extends downward, and the lower end of the vertical extension rod passes through the reserved hole on the basement top plate and extends out of the lower side of the basement top plate.
[0015] Furthermore, it also includes several second buffer components, which include a second positioning tube and a second base plate. One end of the second base plate is fixedly connected to the side wall of the vertical extension rod extending from the lower side of the basement top plate, and the other end of the second base plate extends to the outside of the vertical extension rod. The lower end of the second positioning tube is fixedly connected to the second base plate, and the buffer spring is placed in the second positioning tube. The upper end of the buffer spring contacts the lower end surface of the basement top plate.
[0016] Furthermore, the first buffer assembly also includes a first limiting tube, which is fixedly connected to the first base plate, the first limiting tube is located inside the first positioning tube, the height of the first limiting tube is lower than the height of the first positioning tube, and the buffer spring is installed between the first positioning tube and the first limiting tube.
[0017] This product uses a new type of buffer base for construction elevators. It is designed for the situation where the equipment foundation base is installed on the basement floor. The construction elevator cage can only stay above the basement top plate, and the buffer spring cannot be installed. When the cage stalls and falls, it is easy to cause equipment deformation and top plate damage. Now we design a new base and install buffer springs to complete the safety protection work.
[0018] The problem that some cargo construction elevators installed above the basement floor cannot be installed with buffer springs has been solved, and safety protection has been implemented for the cargo construction elevators and the main structure of the building.
[0019] The beneficial effects of the new type of cushioning base for construction hoists are:
[0020] (1) Enhanced safety: The dual buffer design of the first buffer component and the second buffer component effectively absorbs the impact force when the elevator stalls and falls, protecting the elevator structure from damage. At the same time, it reduces the impact on the basement roof and prevents structural damage.
[0021] (2) Strong adaptability: This base is suitable for installation on the basement floor. It can pass through the standard section through the reserved hole in the special scenario. There is no need for additional reinforcement of the basement top plate, which reduces construction cost and complexity.
[0022] (3) Easy to install and maintain: The first support rod and the second support rod are connected by bolts, which are easy to disassemble and reassemble to meet the needs of different construction sites and are convenient for daily inspection and maintenance.
[0023] (4) Economical and practical: By optimizing the structural design, the material utilization rate is improved, the production cost is reduced, and the stability and reliability of long-term use are guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The two first support rods 100 and the two second support rods 200 are both made of rectangular square steel. The two first support rods 100 and the two second support rods 200 are arranged opposite each other and connected at their ends to form a rectangular frame 300. The rectangular frame 300 is mounted on the outside of the standard section 710 of the freight construction elevator and placed at the edge of the reserved opening in the basement ceiling 700. The first support rods 100 and the second support rods 200 are detachably connected by bolts. The rectangular frame 300 is mounted on the outside of the standard section 710 of the freight construction elevator and placed at the edge of the reserved opening in the basement ceiling 700.
[0036] Each first support rod 100 is provided with two groups of first buffer components, and the first buffer component includes a first positioning tube 410, a first limiting tube 420, a first reinforcing rib 440 and a first bottom plate 430. One end of the first bottom plate 430 is welded and fixed to the side wall of the first support rod 100, and the other end of the first bottom plate 430 extends to the outside of the first support rod 100. The lower end of the first positioning tube 410 is fixedly connected to the first bottom plate 430, and the first positioning tube 410 and the first support rod 100 are also welded and fixed by the first reinforcing rib 440.
[0037] The first position limiting tube 420 is fixedly connected to the first base plate 430. The first position limiting tube 420 is located inside the first positioning tube 410. The height of the first position limiting tube 420 is lower than the height of the first positioning tube 410. The buffer spring 500 is installed between the first positioning tube 410 and the first position limiting tube 420. The upper end of the buffer spring 500 extends out from the upper side of the first positioning tube 410. The first buffer component is located outside the rectangular frame 300.
[0038] The two groups of vertical extension rods 800 correspond one-to-one to the two first support rods 100. Each group of vertical extension rods 800 includes two vertical extension rods 800. The vertical extension rods 800 are fixedly connected to the side walls of the corresponding first support rods 100. The vertical extension rods 800 are located on the inner side of the rectangular frame 300. The distance between the two vertical extension rods 800 in the same group corresponds to the width of the standard section 710 of the cargo construction elevator. The vertical extension rods 800 extend downward, and the lower ends of the vertical extension rods 800 pass through the reserved holes on the basement top plate 700 and extend out from the lower side of the basement top plate 700.
[0039] The second buffer assembly includes a second positioning tube 610, a second reinforcement rib 630 and a second base plate 620. One end of the second base plate 620 is fixedly connected to the side wall of the vertical extension rod 800 extending from the lower side of the basement top plate 700, and the other end of the second base plate 620 extends outward from the vertical extension rod 800.

The upper end of the buffer spring 500 is in contact with the lower end surface of the basement top plate 700. The second positioning tube 610 and the vertical extension rod 800 are also welded and fixed by the second reinforcement rib 630.
[0040] During normal installation and use of a construction hoist, the foundation base is installed on the backfill soil or above the basement ceiling 700°. The foundation base can then be installed and used normally. Installation on backfill soil or the basement ceiling 700° poses insufficient bearing capacity and is prone to sinking. Foundations above the basement ceiling 700° require calculated reinforcement, a complex and costly process. Currently, some projects place the foundation on the basement floor, reserve an opening above the basement ceiling 700°, pass the standard section 710 through the reserved opening, and then install the entire machine. A fence is installed above the basement ceiling 700°. Because the original foundation base is above the basement floor, a new buffer base is installed for this construction hoist to prevent collisions with the elevator cage.
[0041] The above is only one embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the principles of the present invention, and these should also be regarded as falling within the scope of protection of the present invention.
