Description

Technical Field

[0001] This utility model relates to a lifting platform, specifically a lifting platform with an all-around protective structure. Background Technology

[0002] The primary purpose of a lifting platform is to raise the object vertically, facilitating transport to higher places or enabling workers to perform construction tasks. The vertical lifting height varies depending on the specific height requirement. To ensure construction safety and prevent accidents such as falls from the lifting platform, side guardrails are typically added.

[0003] Referring to Chinese patent publication CN104495684A, published on 2015-04-08, a self-propelled track lifting platform is disclosed, relating to the field of lifting technology, to solve the problem that existing mobile scissor lifts cannot cross high heights and move on fixed tracks. The self-propelled track lifting platform provided by this invention includes a base, a first support rod and a second support rod arranged in an "X" shape, and a top plate disposed on the upper part of the two support rods. Support legs are provided at the bottom of the base, and track wheels are provided at the lower part of the support legs. The track wheels can roll on a track laid on the ground to drive the movement of the lifting part. A motor and transmission mechanism are provided on the base to transmit the rotational motion of the motor to the track wheels. A guardrail is provided on the top plate to protect the operator. This invention can move back and forth along the product production process, and is flexible and easy to operate.

[0004] The shortcoming of the existing technology is that the added side guardrails can, to some extent, interfere with the freedom of operation. Specifically, the lifting platform has three sides welded together, with one side having a gate to allow workers or goods to enter. However, when working at heights, once the materials on the lifting platform are used up, they need to be hoisted again. The hoisted materials can either enter through the gate or cross the guardrails before being placed onto the lifting platform. Utility Model Content

[0005] The purpose of this invention is to provide a lifting platform with an all-around protective structure to overcome the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting platform with an all-round protection structure, including a four-wheel walking mechanism and a lifting platform, and a scissor-type lifting bracket is fixedly installed between the two. The lifting platform includes a main platform and a horizontal moving platform, and its upper surface is welded with three side panels distributed along the edge.

[0007] The horizontal moving platform is slidably disposed on the top of the main platform and is driven to move at the opening of the three sides.

[0008] The upper surface of the horizontal moving platform is welded with symmetrically distributed side bases, and also includes a first side guard, which includes at least two pins, and the pins are slidably connected to the sliding groove sheet metal fixedly installed on the side base.

[0009] The slide plate is provided with first insertion holes distributed at adjacent ports, and the pin is provided with second insertion holes distributed at adjacent bottoms;

[0010] A notch is provided on one side of the adjacent port of the slide rail sheet metal. When the first insertion hole and the second insertion hole are coaxial, the two first side guards flip towards each other.

[0011] Preferably, two of the three side panels are symmetrically welded with connecting legs, and two connecting legs located on the same side panel are hinged with second side guards.

[0012] Preferably, a third side guard is rotatably provided between the connecting legs on the two side enclosures, and is perpendicular to the flipping direction of the second side guard.

[0013] Preferably, the outer walls of the third side guard and the first side guard on opposite sides are respectively welded with groove-shaped sheet metal parts, and the second side guard is embedded in the groove-shaped sheet metal parts in a vertical state;

[0014] The sidewalls of adjacent ports of the groove-shaped sheet metal part are provided with through grooves, and a stop shaft is welded in the center of the through groove. It also includes a ring body located in the through groove and sleeved on the outside of the stop shaft.

[0015] The inner radius of the ring is several times the circumference of the outer wall of the retaining shaft.

[0016] Preferably, a fourth side guard is rotatably disposed on the horizontal moving platform between the two first side guards, and the fourth side guard is embedded in the groove-shaped sheet metal part in a vertical state.

[0017] Preferably, a side door is hinged to the third side guard.

[0018] Preferably, the horizontal moving platform is fixedly provided with an injection-molded protective plate on one side of the upper surface of the main platform.

[0019] Preferably, the horizontal moving platform is provided with guide wheels on both sides that are rotatably connected to the upper surface of the main platform.

[0020] Preferably, one of the three sides of the enclosure has positioning holes arranged in a linear array along the sliding direction of the horizontal moving platform on its end face;

[0021] A locking mechanism is fixedly installed on the horizontal moving platform. The locking mechanism includes a pin that is inserted and assembled with the positioning hole.

[0022] Preferably, the locking mechanism includes a V-shaped component rotatably mounted on the horizontal moving platform, one side of which is universally connected to a ball rod, and the ball rod is rotatably connected to the pin component;

[0023] The end face of the perimeter is fixedly installed with positioning grooves symmetrically distributed about the positioning holes.

[0024] In the above technical solution, the lifting platform with an all-round protection structure provided by this utility model has the following effects: the lifting platform is composed of a main platform and a horizontal moving platform, and the working surface of the lifting platform can be extended according to actual needs to meet the operation requirements.

[0025] Secondly, the vertical height of the first side guardrails on both sides of the horizontal moving platform can be adjusted relative to the slide rail sheet metal, or it can be moved to its maximum vertical height and then rotated around the pivot point of the pin that is coaxially connected to the first and second insertion holes, thereby eliminating one or both of the first side guardrails to facilitate the hoisting of materials. During this operation, workers can stand on the main platform with guardrails. Safety is fully considered while ensuring ease of operation. Attached Figure Description

Detailed Implementation

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] Please see Figure 1-5 This utility model provides a technical solution: a lifting platform with an all-around protective structure, including a four-wheel walking mechanism 1 and a lifting platform 2, with a scissor-type lifting bracket 8 fixedly installed between them. The four-wheel walking mechanism 1 includes an electric drive system, which can be controlled by an external remote control to drive the four-wheel walking mechanism 1 to move. This is prior art and will not be disclosed in detail. The lifting platform 2 is raised by the scissor-type lifting bracket 8, which is known technology, so its detailed structure will not be elaborated further. The improvement of this application lies in the lifting platform 2, which includes the following detailed embodiments:

[0036] Example 1

[0037] Combination Figure 1 As shown, the lifting platform 2 includes a main platform 21 and a horizontal moving platform 22. The working surface of the lifting platform 2 can be extended according to actual needs to meet operational requirements. Furthermore, an injection-molded protective plate is fixedly installed on the side of the horizontal moving platform 22 located on the upper surface of the main platform 21. The purpose of this installation is to prevent workers' shoes from getting caught in the gap between the horizontal moving platform 22 and the main platform 21.

[0038] Furthermore, guide wheels 5 are rotatably mounted on both sides of the horizontal moving platform 22 and are rolledly connected to the upper surface of the main platform 21.

[0039] Furthermore, a three-sided perimeter 24 distributed along the edge is welded to the upper surface of the main platform 21, and the horizontal moving platform 22 is slidably disposed on the top of the main platform 21 and is driven to move through the opening of the three-sided perimeter 24. That is to say, the three-sided perimeter 24 here serves as a guide rail groove, thereby providing guidance for the movement of the horizontal moving platform 22. The movement of the horizontal moving platform 22 can be driven by an electric push rod, an electric lead screw, or a driving method known to those skilled in the art, but manual pushing is preferred.

[0040] Then, positioning holes 9 are provided on the end face of one of the three side panels 24, arranged in a linear array along the sliding direction of the horizontal moving platform 22. Next, a locking mechanism 7 is fixedly installed on the horizontal moving platform 22, the locking mechanism 7 including a pin 71 that is inserted and assembled with the positioning holes 9.

[0041] The aforementioned linearly arrayed positioning holes 9 are distributed on at least one side perimeter, or symmetrically on two side perimeters. They are then secured using a pin method, i.e., the pin 71 is inserted into the positioning holes 9. In short, the expansion of the working surface formed by the main platform 21 and the horizontal moving platform 22 is of a predetermined specification, primarily determined by the number of positioning holes 9 and the spacing between adjacent positioning holes 9.

[0042] Example 2

[0043] Based on the above embodiment one, combined with Figure 4 As shown, the locking mechanism 7 includes a V-shaped component 72 rotatably mounted on the horizontal moving platform 22. One side of the V-shaped component 72 is universally connected to a ball rod 73, which is rotatably connected to a pin 71. Positioning grooves 10, symmetrically distributed around the positioning holes 9, are fixedly installed on the end face of the side. Specifically, because the ball rod 73 and the pin 71 are rotatably connected, when a worker steps on the V-shaped component 72, causing it to tilt (i.e., the pin 71 disengages from the positioning hole 9), the pin 71 is deflected by the positioning grooves 10 as the horizontal moving platform 22 moves, thus disengaging from one positioning groove 10 and moving to another, where it remains vertical due to the positioning groove 10's restriction. Releasing the foot from stepping on the V-shaped component 72 causes it to return to its original position under the action of a torsion spring or tension spring. Figure 4 When in the indicated state, the pin 71 is inserted into the positioning hole 9, thereby locking the movement of the main platform 21 and the horizontal moving platform 22.

[0044] Example 3

[0045] Based on the above embodiment one, combined with Figure 2As shown, the upper surface of the horizontal moving platform 22 is welded with symmetrically distributed side bases 221, and also includes first side guards 222, which include at least two pins 223. The pins 223 are slidably connected to the slide rail sheet metal 224 fixedly installed on the side bases 221. The slide rail sheet metal 224 has first insertion holes distributed at adjacent ports, and the pins 223 have second insertion holes distributed at adjacent bottoms. Furthermore, a notch 2241 is provided on one side of the adjacent ports of the slide rail sheet metal 224. When the first insertion hole and the second insertion hole are coaxial, the two first side guards 222 flip towards each other. The vertical height of the oppositely distributed first side guards 222 on the horizontal moving platform 22 can be changed with respect to the slide rail sheet metal 224, or it can be moved to the maximum vertical height and then rotated around the pin that is coaxially inserted with the first insertion hole and the second insertion hole, thereby eliminating one or both of the first side guards 222 to facilitate the lifting of materials. During this operation, workers can stand on the main platform 21, which is equipped with guardrails. Safety is fully considered while ensuring ease of operation.

[0046] Example 4

[0047] Based on the above embodiments, combined with Figure 2 As shown, two of the three side panels 24 are symmetrically welded with connecting legs 225, and two connecting legs 225 located on the same side panel are hinged with second side guards 227.

[0048] Secondly, a third side guard 226 is rotatably provided between the connecting legs 225 on the two sides, and is perpendicular to the flipping direction of the second side guard 227.

[0049] Furthermore, a fourth side guard 228 is rotatably mounted on the horizontal moving platform 22, distributed between the two first side guards 222.

[0050] The locking of the aforementioned second side guard 227 and fourth side guard 228 is achieved through the slotted sheet metal part 6, combined with... Figure 2 and Figure 3 As shown, a through groove is provided on the side wall of the adjacent port of the groove-shaped sheet metal part 6, and a stop shaft 31 is welded in the center of the through groove. It also includes an annular body 32 located in the through groove and sleeved on the outside of the stop shaft 31. The inner radius of the annular body 32 is several times the outer circumference of the stop shaft 31.

[0051] Specifically, during implementation, when the two rings 32 are in contact with each other, it means that the axis of the ring 32 is deviated from the stop shaft 31. That is, the part of the ring 32 inside the grooved sheet metal part 6 is larger than the part outside the grooved sheet metal part 6. At this time, under the action of gravity, they lean against each other, thereby blocking the second side guard 227 and the fourth side guard 228.

[0052] It should be noted that a side door 2261 is hinged to the third side guard 226 mentioned above, so that workers can enter the lifting platform 2.

[0053] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
