Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a construction lifting platform vehicle capable of climbing stairs. Background Art

[0002] In modern construction projects, stairs are necessary building design components for connecting larger vertical distances. During construction, bricklaying, plastering and other work at the stair section position requires setting up temporary scaffolding at the stair section position for operation.

[0003] During the construction process, problems such as the operating frame being difficult to move and the erection being irregular often occur, posing safety hazards. Material transportation and construction work require manual labor, which consumes a lot of time and effort.

[0004] The existing lifting operation platform can only be moved and lifted on a flat ground and cannot be used on stairs. Summary of the invention

[0005] The content of the present invention is used to introduce the concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of the present disclosure is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] Some embodiments of the present invention provide a construction lifting platform vehicle that can climb stairs to solve the technical problems mentioned in the above background technology section.

[0007] The construction lifting platform vehicle capable of climbing stairs comprises a climbing mechanism, a level adjustment mechanism, a lifting mechanism and a working platform connected in sequence from bottom to top, wherein:

[0008] The stair climbing mechanism is used for climbing stairs;

[0009] One end of the horizontal adjustment mechanism is hinged to the stair climbing mechanism, and the other end is connected to the stair climbing mechanism at an adjustable angle, so as to make the lifting mechanism and the working platform in a horizontal state when the stair climbing mechanism is in an inclined state;

[0010] The lifting mechanism is used to lift the working platform;

[0011] The working platform is used for construction by workers and placement of materials.

[0012] Optionally, the stair climbing mechanism includes a frame and climbing wheels, front wheels, rear wheels and a sleeved track connected to both sides of the frame, wherein the climbing wheels are higher than the front wheels.

[0013] Optionally, the outer side of the track is serrated, and the inner angle and the outer angle are both 90°.

[0014] Optionally, the outside of the crawler belt is wrapped with an elastic rubber crawler belt.

[0015] Optionally, the horizontal adjustment mechanism includes a hydraulic rod, an adjustment support rod, and a horizontal sensor. The hydraulic rod is fixedly arranged on the stair-climbing mechanism. The telescopic end of the hydraulic rod is rotatably connected to one end of the adjustment support rod, and the other end of the adjustment support rod is hinged to the bottom of the horizontal sensor.

[0016] Optionally, the horizontal sensor is arranged as a "U"-shaped groove body, and the lifting mechanism is placed inside the horizontal sensor.

[0017] Optionally, the side walls and the bottom on both sides of the horizontal sensor are filled with liquid, and floats are placed inside the side walls on both sides.

[0018] Optionally, when the stair-climbing mechanism is in an inclined state while climbing the stairs, the liquid levels on both side walls of the horizontal sensor change, and two floats generate electrical signals. The hydraulic rod drives the adjustment support rod according to the electrical signals, so that the horizontal sensor is in a horizontal state.

[0019] Optionally, a leg assembly is respectively pivotally connected to both sides of the bottom of the lifting mechanism for supporting on the ground; each leg assembly includes a rotating shaft, an inner rod, and an outer rod. The inner rod is rotatably connected to the lifting mechanism through the rotating shaft; the inner rod is inserted into the outer rod and is threadedly connected to the outer rod.

[0020] Optionally, a support footrest is further fixedly arranged on the outer rod.

[0021] The above embodiments of the present invention have the following beneficial effects: Through the stair-climbing construction lifting platform vehicle of the present invention, it is possible to realize traveling on the ground and climbing stairs, thereby improving work efficiency and reducing labor costs.

[0022] Specifically, the stair-climbing mechanism can drive the platform vehicle to move on the ground and climb stairs, thereby driving the working platform to move near the stairs and climb the stairs, so that the working platform reaches the construction position. Thus, the work of erecting a scaffolding is saved, the labor cost is reduced, and the work efficiency is also improved.

[0023] In addition, when the stair-climbing mechanism is in an inclined state while climbing the stairs, the horizontal adjustment mechanism can rotate around the hinge axis of the stair-climbing mechanism, thereby adjusting the angle with the stair-climbing mechanism, so that the working platform is in a horizontal state. In this way, the risk of the working platform tilting and causing the staff or materials to fall can be avoided, and the safety and reliability of the platform vehicle are improved.

[0038] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0039] First see Figure 1 and Figure 2 , Figure 1 It is a structural schematic diagram of an embodiment of the present invention of a construction lifting platform vehicle capable of climbing stairs in a driving state; Figure 2 FIG. 1 is a structural schematic diagram of an embodiment of the present invention of a construction lifting platform vehicle capable of climbing stairs in a climbing state. Figure 1 and Figure 2 As shown, the climbing construction lifting platform vehicle is moved from bottom to top ( Figure 1 The invention relates to a method for constructing a stair climbing machine (in the direction of the stair climbing machine) and a stair climbing mechanism 1, a horizontal adjustment mechanism 2, a lifting mechanism 3 and a working platform 4 connected in sequence. The stair climbing mechanism 1 is used for climbing stairs, and the horizontal adjustment mechanism 2 is used for adjusting the lifting mechanism 3 and the working platform 4 when the stair climbing mechanism 1 is in an inclined state when climbing stairs, so that the working platform 4 is in a horizontal state. The lifting mechanism 3 is used for lifting the working platform 4. Workers can stand in the working platform 4 to carry out construction.

[0040] See next Figure 3 And continue to read Figure 1 and Figure 2 , Figure 3 The structural schematic diagram of an embodiment of the stair-climbing mechanism of the present invention. As Figures 1 to 3 shown, the stair-climbing mechanism 1 includes a vehicle frame and climbing wheels 11, front wheels 12, and rear wheels 13 connected to both sides of the vehicle frame. The climbing wheels 11, front wheels 12, and rear wheels 13 are arranged in sequence from front to back ( Figure 3 from right to left as shown). In Figure 1 the traveling state of the platform vehicle on flat ground as shown, the climbing wheels 11 are higher than the front wheels 12. The above-mentioned climbing wheels 11, front wheels 12, and rear wheels 13 are sleeved with a crawler 14 to form an L-shaped stair-climbing mechanism 1. In the stair-climbing state, since the crawler 14 between the climbing wheels 11 and the front wheels 12 is inclined, the crawler 14 in this section can bite into the stairs. Under the rotation of the crawler 14, the stair-climbing action is completed, and the entire stair-climbing mechanism 1 gradually climbs onto the stairs.

[0041] The outer side of the above-mentioned crawler 14 is tooth-shaped, and both the internal angle and the external angle are 90°, so as to ensure the biting degree when climbing the stairs. Further, the external part of the tooth-shaped crawler 14 can also be wrapped with an elastic rubber crawler 14 to avoid damage to the ground or stairs during the traveling state and the stair-climbing state.

[0042] It should be noted that the stair-climbing mechanism 1 further includes a hydraulic drive system or a motor drive system for driving the climbing wheels 11, front wheels 12, and rear wheels 13. Those skilled in the art can select according to the actual situation, and no limitation is made here.

[0043] Next, please refer to Figure 4 and continue to refer to Figure 1 and Figure 2 , Figure 4 The structural schematic diagram of an embodiment of the horizontal adjustment mechanism of the present invention. As Figure 1 and Figure 4 shown, the above-mentioned horizontal adjustment mechanism 2 includes a hydraulic rod 22 installed on the vehicle frame of the above-mentioned stair-climbing mechanism 1. The telescopic end of the hydraulic rod 22 can reciprocally extend and retract along the direction parallel to the connection line of the front wheels 12 and the rear wheels 13. The telescopic end of the hydraulic rod 22 is hinged with an adjustment support rod 23, and the other end of the adjustment support rod 23 is hinged with the left end of the bottom of the horizontal sensor 21 ( Figure 4 the direction in

[0044] The above-mentioned horizontal sensor 21 can be set as a "凵"-shaped groove body, and the above-mentioned lifting mechanism 3 can be placed in this groove body. The two side walls and the bottom of this groove body can be hollow and filled with part of the liquid. On the left and right sides ( Figure 4A float is arranged inside the side wall (in the direction in the direction). When the platform vehicle is in the state of climbing stairs, the climbing mechanism 1 will tilt, so that the liquid level on the left side of the horizontal sensor 21 rises and the liquid level on the right side drops. The float can be a magnet wrapped with rubber or silicone. When the height of the float changes, the magnetic field changes, thereby generating an electrical signal. Specifically, a Hall sensor can be arranged outside the left and right side walls to detect the change of the magnetic field of the float and generate an electrical signal. Of course, those skilled in the art can also determine the change of the magnetic field of the float and generate an electrical signal based on common knowledge.

[0045] It should be noted that, in order to improve the supporting strength of the horizontal adjustment mechanism, two or more hydraulic rods 22 and adjusting support rods 23 may be arranged in parallel.

[0046] The platform vehicle may also include a controller, such as a PLC (Programmable Logic Controller). The controller may receive electrical signals generated by floats on both sides, thereby determining the heights of the two floats, and thus determining the inclination of the level sensor 21. The controller may also be connected to the hydraulic rod 22 for communication. The controller may control the telescopic end of the hydraulic rod 22 to extend to the left ( Figure 4 The horizontal sensor 21 is supported by the adjusting support rod 23, and the horizontal sensor 21 is supported by the adjusting support rod 23, so that the ...

[0047] The lifting mechanism 3 can adopt a variety of lifting mechanisms 3 that are currently widely used, such as a scissor-type lifting mechanism, a rack and pinion lift, a chain lift, etc., and those skilled in the art can choose according to actual conditions.

[0048] The working platform 4 may be a guardrail platform with an opening and closing door for workers to perform high-altitude operations and place materials.

[0049] See also Figure 5 And continue to read Figure 1 , Figure 5 FIG. 2 is a schematic structural diagram of an embodiment of a leg assembly of the present invention. Figure 5 As shown, when the platform vehicle reaches the construction location, in order to further fix the platform vehicle, a leg assembly 5 can be respectively provided on both sides of the bottom of the lifting mechanism 3. The leg assembly 5 includes a rotating shaft 51, an inner rod 52, an outer rod 53 and a support foot 54. The inner rod 52 is rotatably connected to the lifting mechanism 3 through the rotating shaft 51. The right end of the inner rod 52 ( Figure 5The inner rod 52 and the outer rod 53 are inserted into the outer rod 53 and are threadedly connected to the left end of the outer rod 53. A support leg 54 is fixed to the right end of the outer rod 53. In the working state, the support leg 54 can be rotated by the rotating shaft 51, and the overall length of the inner rod 52 and the outer rod 53 can be adjusted by the thread, so that the support leg 54 is closely supported by the ground and fixed.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
