Description

Technical Field

[0001] This invention relates to the technical field of construction elevators, and more particularly to a self-balancing floating variable travel construction elevator. Background Technology

[0002] Construction elevators are commonly referred to as construction hoists. A typical construction elevator consists of several parts, including a car, drive mechanism, standard sections, wall attachments, chassis, railings, and electrical system. It is a type of construction machinery frequently used in construction for carrying people and goods.

[0003] Existing construction elevators are usually used in conjunction with tower cranes on construction sites. When lifting the elevator, the tower crane needs to be connected to the elevator. The operation requires people to stand on top of the elevator to lift it, which has a low safety factor. Moreover, when the tower crane lifts the elevator, there is no rope stabilization structure, which causes the self-balancing floating car to shift and has poor stability. In addition, the top of the added assembly frame is prone to debris accumulation, and cleaning is required during assembly, making the elevator installation cumbersome and complicated. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the current self-balancing floating variable stroke construction elevator, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a self-balancing floating variable travel construction elevator.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a self-balancing floating variable stroke construction elevator, comprising: an elevator lifting unit, including a splicing frame, a support top frame disposed on the splicing frame, a self-balancing component disposed on the support top frame, and a power winch disposed on one side of the splicing frame and connected to the self-balancing component; and a lifting unit, including a hydraulic component disposed within the support top frame, a delayed tensioning component disposed on the support top frame, and a limiting component disposed on the support top frame.

[0008] As a preferred embodiment of the cable winding device of the present invention, the self-balancing component includes a support pulley disposed on the support top frame, a support block disposed on the support top frame, a support wheel disposed in the support block, a car disposed on the splicing frame, and an extension winch disposed on the top side of the car and a connecting rope connected to the extension winch.

[0009] In a preferred embodiment of the cable winding device of the present invention, the hydraulic assembly includes a hydraulic rod disposed within the support top frame and a contact plate disposed on the hydraulic rod.

[0010] As a preferred embodiment of the cable winding device of the present invention, the delayed stretching assembly includes a connecting plate disposed on the outer wall of the supporting top frame, a support plate disposed on the contact plate, a sliding track disposed on the top of the support plate, a slider disposed inside the sliding track, a winding wheel disposed on the slider, a torsion spring disposed at the end of the winding wheel, and a winding rope disposed on the winding wheel and connected to the connecting plate.

[0011] In a preferred embodiment of the cable winding device of the present invention, the limiting component includes a receiving plate disposed on the top support frame, a return spring disposed in the receiving plate, a horizontal plate disposed on the return spring, a pin disposed on the horizontal plate, a guide wheel disposed on the receiving plate, a slot disposed on the top support frame, and a pull rope disposed on the horizontal plate and connected to the bottom of the slider.

[0012] As a preferred embodiment of the cable winding device of the present invention, it further includes a locking unit, which includes a locking mechanism disposed on one side of the support block; and a triggering mechanism disposed inside the support top frame.

[0013] In a preferred embodiment of the cable winding device of the present invention, the locking mechanism includes a locking block disposed on the support block, a movable plate disposed within the locking block, a tension spring disposed within the locking block and connected to the movable plate, a locking rod disposed on the movable plate, a cooperating block disposed within the support block, and a pull plate disposed on the locking block and connected to the movable plate.

[0014] As a preferred embodiment of the cable winding device of the present invention, the triggering mechanism includes a chute disposed in the top support frame, a pressing plate disposed on the contact plate, a pressure plate disposed in the chute, a steering wheel disposed in the chute, and a through rope disposed on the pressure plate and connected to the pull plate.

[0015] As a preferred embodiment of the cable winding device of the present invention, it further includes a cleaning unit, which includes an air storage assembly disposed on the top of the contact plate; an air jet assembly disposed inside the contact plate; the air storage assembly includes an air storage column disposed on the contact plate, a piston disposed in the air storage column, a top rod disposed on the piston and connected to the support top frame, an air inlet disposed on the air storage column, and a one-way valve disposed in the air inlet.

[0017] The beneficial effects of this invention are as follows: The lifting unit raises the supporting top frame, and at the same time, it drives the limiting component, so that the limiting component restricts the supporting top frame when it is at its highest point. At this time, the lifting unit can be retracted, and the assembly frame can be installed in the retracted area. When the lifting unit retracts, its cleaning unit shell cleans the assembly frame, and the locking unit can lock the self-balancing component to prevent deviation. As a result, the elevator is smooth and stable during the lifting stroke, and the dangerous working time of workers is reduced, which greatly improves safety. Attached Figure Description

[0032] Example 1

[0033] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 A schematic diagram of the overall structure of a self-balancing floating variable stroke construction elevator is provided, as shown below. Figure 1 A self-balancing floating variable stroke construction elevator includes an elevator lifting unit 100 and a lifting unit 200.

[0034] Specifically, the elevator lifting unit 100 includes a splicing frame 101, a support top frame 102 mounted on the splicing frame 101, a self-balancing component 103 mounted on the support top frame 102, and a power winch 104 mounted on one side of the splicing frame 101 and connected to the self-balancing component 103. Two sets of power winches 104 are installed on the ground and used as the power source for elevator lifting. Two sets of cars 103d are connected through the self-balancing component 103, so that the two sets of cars 103d achieve weight balance and do not need to be set up separately as a counterweight. The inner wall of the support top frame 102 matches the outer diameter of the splicing frame 101, so that the support top frame 102 can move along the splicing frame 101.

[0035] Furthermore, the lifting unit 200 includes a hydraulic component 201 disposed within the support top frame 102, a delayed stretching component 202 disposed on the support top frame 102, and a limiting component 203 disposed on the support top frame 102. The hydraulic component 201 is installed on the inner top wall of the support top frame 102. The top end of the delayed stretching component 202 is connected to the outer wall of the support top frame 102, and the bottom end of the delayed stretching component 202 is connected to the limiting component 203. The delayed stretching component 202 pulls the interior of the limiting component 203 to move.

[0036] Furthermore, the self-balancing assembly 103 includes a support pulley 103a mounted on the support top frame 102, a support block 103b mounted on the support top frame 102, a support wheel 103c mounted inside the support block 103b, a car 103d mounted on the splicing frame 101, and an extension winch 103e mounted on the top side of the car 103d and connected to the extension winch 103e by a connecting rope 103f. The support wheel 103c and the support pulley 103a are used to ensure the movement of the connecting rope 103f. Six sets of support blocks 103b are respectively installed on the outer walls of both sides of the support top frame 102. Support wheels 103c are installed on the inner walls of both sides of the support blocks 103b. An extension winch 103e is installed on the top of the car 103d. The extension winch 103e is used to wind up the connecting rope 103f, so that the car 103d can adapt to the splicing frame 101 after the travel height is increased.

[0037] Furthermore, the hydraulic assembly 201 includes a hydraulic rod 201a disposed within the support top frame 102 and a contact plate 201b disposed on the hydraulic rod 201a. The hydraulic rod 201a is installed on the inner top wall of the support top frame 102, and the contact plate 201b is installed on the telescopic end of the hydraulic rod 201a. The telescopic movement of the hydraulic rod 201a drives the contact plate 201b to move, and the contact plate 201b can contact the top of the splicing frame 101.

[0038] Furthermore, the delayed stretching assembly 202 includes a connecting plate 202a disposed on the outer wall of the supporting top frame 102, a support plate 202c disposed on the contact plate 201b, a sliding track 202d disposed on the top of the support plate 202c, a slider 202e disposed inside the sliding track 202d, a take-up wheel 202f disposed on the slider 202e, a torsion spring 202g disposed at the end of the take-up wheel 202f, and a take-up rope 202h disposed on the take-up wheel 202f and connected to the connecting plate 202a, supporting the top frame. A connecting plate 202a is installed on the outer wall of 102. A winding rope 202h is installed at the bottom of the connecting plate 202a. A support plate 202c is installed on the outer wall of the contact plate 201b. A sliding track 202d is installed at the bottom of the support plate 202c. A slider 202e is installed on the inner wall of the sliding track 202d. The outer wall of the slider 202e is in contact with the inner wall of the arc track. A winding wheel 202f is installed on the top of the slider 202e. The winding wheel 202f is used to wind up the winding rope 202h. A torsion spring 202g at the end of the winding wheel 202f is used to restore the winding wheel 202f.

[0039] Furthermore, the limiting component 203 includes a receiving plate 203a disposed on the supporting top frame 102, a return spring 203b disposed within the receiving plate 203a, a horizontal plate 203c disposed on the return spring 203b, a pin 203d disposed on the horizontal plate 203c, a guide wheel 203e disposed on the receiving plate 203a, a slot 203g disposed on the supporting top frame 102, and a pull rope 203f disposed on the horizontal plate 203c and connected to the bottom of the slider 202e. The return spring 203b is used to reset the moved pin 203d. One end of the return spring 203b is installed on the inner wall of the receiving plate 203a, and the other end is connected to the horizontal plate 203c. The pin 203d is installed on the outer wall of the horizontal plate 203c. The guide wheel 203e is used to turn the pull rope 203f, and the pull rope 203f is made of a material with a certain elasticity.

[0040] Operation process: As the stroke increases, the hydraulic component 201 extends, and the hydraulic rod 201a drives the contact plate 201b to move. When the contact plate 201b is not in contact with the splicing frame 101, the delayed tensioning component 202 begins to pull the movement of the limiting component 203, and the winding rope 202h on its winding reel 202f is pulled out from the winding reel 202f. When the contact plate 201b begins to apply pressure to the splicing frame 101 and lifts the supporting top frame 102, the winding rope 202h is fully pulled out. When slider 202e pulls pull rope 203f, pull rope 203f pulls pin 203d to move, causing pin 203d to gradually move out of receiving plate 203a. When the inclined surface of pin 203d is pressed against the bottom side of the connection point of splicing frame 101, pin 203d is pressed into receiving plate 203a. At this time, pull rope 203f is stretched and stores force. When pin 203d moves to the top side of the connection point of splicing frame 101, the stretched pull rope 203f pushes pin 203d back into the receiving plate 203a. Pulling out pin 203d causes it to spring into slot 203g. At this time, hydraulic rod 201a shortens, and the weight of the top frame 102 it supports is transferred to the splicing frame 101 through pin 203d. The new splicing frame 101 can then be placed and installed within the shortened area of ​​hydraulic rod 201a. When hydraulic rod 201a drives contact plate 201b to shorten, its winding rope 202h and pulling rope 203f are in a slack state. When hydraulic rod 201a resumes supporting the weight of top frame 102, its return spring 203b pulls back the pin 203d, which is no longer under force. This completes the installation of one splicing frame 101. At this time, hydraulic component 201 extends again, raising the hydraulic component 201 based on the newly added splicing frame 101, thereby completing continuous stroke increase. This allows the variable stroke engineering elevator to complete the lifting action automatically, making the elevator stroke increase convenient and simple, eliminating the need for a tower crane for stroke increase, and improving safety.

[0041] Example 2

[0042] Reference Figure 3 , Figure 4 and Figure 7 This embodiment differs from the above embodiments in that it also includes a locking unit 300, which includes a locking mechanism 301, which is disposed on one side of the support block 103b; and a triggering mechanism 302, which is disposed inside the support top frame 102. The outer wall of the support block is fixedly connected to the locking mechanism, and the triggering mechanism is opened inside the support top frame. The triggering mechanism is used to control the operation of the locking mechanism.

[0043] Specifically, the locking mechanism 301 includes a locking block 301a disposed on the support block 103b, a movable plate 301b disposed within the locking block 301a, a tension spring 301c disposed within the locking block 301a and connected to the movable plate 301b, a locking rod 301d disposed on the movable plate 301b, a mating block 301e disposed within the support block 103b, and a pull plate 301f disposed on the locking block 301a and connected to the movable plate 301b. A movable plate 301b is installed on the inner wall of the locking block 301a. The outer wall of the movable plate 301b matches the inner wall of the locking block 301a. A tension spring 301c is used to restore the movable plate 301b. A locking rod 301d passes through the outer wall of the locking block 301a and extends into the interior of the support block 103b. It is located on one side of the mating block 301e. The mating block 301e and the locking rod 301d are located on both sides of the connecting rope 103f. A pull plate 301f is used to drive the movable plate 301b to move.

[0044] Furthermore, the triggering mechanism 302 includes a slide groove 302a disposed in the support top frame 102, a pressing plate 302b disposed on the contact plate 201b, a pressure plate 302c disposed in the slide groove 302a, a steering wheel 302d disposed in the slide groove 302a, and a through rope 302e disposed on the pressure plate 302c and connected to the pull plate 301f. The pressing plate 302b is installed on one outer wall of the contact plate 201b, and the pressing plate 302b is located on the top side of the pressure plate 302c. The steering wheel 302d is used to lay the through rope 302e according to the required line.

[0045] The rest of the structure is the same as in Example 2.

[0046] Operation process: When the top support frame 102 is raised, its pressure block contacts the pressing block. The pressure block moves downward along the slide groove 302a. The movement of the pressure block drives the through rope 302e to move. The movement of the through rope 302e drives the pull plate 301f to move. The movement of the pull plate 301f drives the moving plate 301b to move within the locking block 301a. The movement of the moving plate 301b drives the locking rod 301d to move. The movement of the locking rod 301d attaches the connecting rope 103f to the mating block 301e, thereby preventing the connecting rope 103f from shifting and sliding during the raising process, thus improving the stability during the raising process.

[0047] Example 3

[0048] Reference Figure 3 and Figure 9 This embodiment differs from the above embodiments in that it also includes a cleaning unit 400, which includes an air storage component 401 and an air jet component 402. The air storage component 401 is installed on the top of the contact plate 201b, and the air jet component 402 is provided inside the contact plate 201b.

[0049] Specifically, the jet assembly 402 is disposed inside the contact plate 201b; the gas storage assembly 401 includes a gas storage column 401a disposed on the contact plate 201b, a piston 401b disposed inside the gas storage column 401a, a top rod 401c disposed on the piston 401b and connected to the support top frame 102, an air inlet 401d disposed on the gas storage column 401a, and a one-way valve 401e disposed inside the air inlet 401d. The gas storage column 401a is installed on the top of the contact plate 201b, and the one-way valve 401e allows gas to enter the gas storage column 401a only from the outside, and the gas in the gas storage column 401a will not overflow from the air inlet 401d. The inner wall of the piston 401b is sealed to the inner wall of the gas storage column 401a.

[0050] Furthermore, the jet assembly 402 includes a flow pipe 402a disposed within the contact plate 201b and communicating with the air storage column 401a, a frame-shaped groove 402b disposed within the contact plate 201b and communicating with the flow pipe 402a, and an air outlet 402c disposed within the contact plate 201b and communicating with the frame-shaped groove 402b. The frame-shaped groove 402b is opened along the top edge of the splicing frame 101, and its air outlet 402c is located on the top side of the edge of the splicing frame 101.

[0051] The rest of the structure is the same as in Example 3.

[0052] Operation process: When the contact plate 201b and hydraulic rod 201a extend, gas enters the air storage column 401a through the air inlet 401d. When the contact plate 201b is retracted to prepare for the installation of the next splicing frame 101, the retracted contact plate 201b compresses the gas in the air storage column 401a. The compressed gas is ejected along the flow pipe 402a, the frame groove 402b and the air outlet 402c, causing the top of the splicing frame 101 to be blown by the airflow, thus removing any debris that may be attached. This ensures the splicing frame 101 is firmly installed and that the installation of the splicing frame 101 is not affected by debris.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
