Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a leveling device. Background Technology

[0002] The pallet jack, also known as a leveling jack, is a common construction tool used to move heavy components. Its upper surface is fixed horizontal, making it ideal for moving components that need to remain level during construction. However, in existing technology, it's difficult for workers to ensure the pallet jack's tracks are level when installing them, often resulting in left-right tilting. This causes the upper surface of the pallet jack to be uneven as it moves along the tracks, making it difficult to keep the moved components level. Therefore, we propose a leveling device to solve this problem. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a leveling device that solves the issue of uneven tracks making it difficult to keep components transported by tanks horizontal.

[0004] This utility model is achieved through the following solution: a leveling device, comprising: A protective shell covers the top of the transport tank vehicle. The first and last ends of the protective shell are respectively attached to the first and last ends of the transport tank vehicle, and gaps are left between the left and right sides of the protective shell and the left and right sides of the transport tank vehicle. The four first screw holes all penetrate the protective shell vertically. The four first screw holes are divided into pairs, and the two pairs of first screw holes are symmetrical about the center line of the upper surface of the protective shell. Four screws are screwed into four first screw holes respectively. Each screw has two ends extending out of the corresponding first screw hole. One end of each screw extends into the protective shell to form a bearing part, and the other end extends to the top of the protective shell to form an operating part. By turning the operating parts of the four screws, the length of the bearing part of each screw is controlled so that the upper surface of the protective shell supported by the four bearing parts is in a horizontal position.

[0005] A further improvement of this leveling device is that the upper surface of the transport tank and the contact surfaces of the bearing ends of the four screws with the upper surface of the transport tank are all provided with anti-slip textures.

[0006] A further improvement of the leveling device of this utility model is that the protective shell includes a shell, a receiving cavity and a cover plate. The receiving cavity is opened at the bottom of the shell and extends through one of the two ends of the shell to form an opening. The cover plate is used to seal the opening. The protective shell also includes a fixing component for securing the cover plate to the opening.

[0007] A further improvement of the leveling device of this utility model is that the fixing component includes a second screw hole, a through hole and a bolt. The through hole extends along the thickness direction of the cover plate, and the second screw hole is opened on the housing. The bolt passes through the through hole and is screwed into the second screw hole, so that the cover plate is pressed against the housing to fix the cover plate at the opening.

[0008] A further improvement of the leveling device of this utility model is that the cover plate includes a vertical plate and a horizontal plate, the vertical plate and the horizontal plate are perpendicular to each other, the through hole is opened on the horizontal plate, and the second screw hole is opened at the upper end of the housing. Compared with the prior art, the beneficial effects of this utility model are as follows: This invention controls the length of each screw's bearing end by turning the operating ends of four screws, thereby adjusting the angle of the upper surface of the protective shell supported by the four bearing ends. This allows the transport tank to adapt to components of various angles and types, improving its applicability. At the same time, the components to be transported are placed directly on the protective shell, which also protects the top of the transport tank. Attached Figure Description

[0013] To address the problem of uneven tracks making it difficult to keep components transported by tanks level, this invention provides a leveling device. The following description, in conjunction with specific embodiments and accompanying drawings, further illustrates this leveling device.

[0014] See Figures 1-3 As shown, a leveling device includes: A protective shell covers the upper part of the transport tank 5. The first and last ends of the protective shell are respectively attached to the first and last ends of the transport tank 5, and gaps are left between the left and right sides of the protective shell and the left and right sides of the transport tank 5. The four first screw holes all penetrate the protective shell vertically. The four first screw holes are divided into pairs, and the two pairs of first screw holes are symmetrical about the center line of the upper surface of the protective shell. Four screws 2 are screwed into four first screw holes respectively. Each screw 2 has corresponding first screw holes extending from both ends. One end of each screw 2 extends into the protective shell to form a bearing part, and the other end extends to the top of the protective shell to form an operating part. By turning the operating parts of the four screws 2, the length of the bearing part of each screw 2 is controlled so that the upper surface of the protective shell supported by the four bearing parts is in a horizontal position.

[0015] By adopting the above design, the length of the bearing end of each screw 2 can be controlled by turning the operating ends of the four screws 2. The length of the bearing end of the screw 2 corresponding to the lower part of the transport tank 5 is increased, and the length of the bearing end of the screw 2 corresponding to the higher part of the transport tank 5 is decreased. The gap on both sides can be used to adjust the tilt of the protective shell to change the angle of the upper surface of the protective shell supported by the four bearing ends. This allows the transport tank 5 to adapt to components with different installation angles and types on the left and right, improving the applicability of the transport tank 5. At the same time, the components to be transported are placed directly on the protective shell, which also protects the top of the transport tank 5.

[0016] The upper surface of the transport tank 5 and the contact surfaces between the bearing ends of the four screws 2 and the upper surface of the transport tank 5 are all provided with anti-slip textures.

[0017] By setting anti-slip textures, the bearing end of the screw 2 can be more stably pressed against the upper surface of the transport tank 5, which can prevent the protective shell from slipping relative to the transport tank 5 during the transport process due to the gaps left between the left and right sides of the protective shell and the left and right sides of the transport tank 5, thus improving stability.

[0018] Further, see Figure 1-2 In this embodiment, the top of the housing 1 is provided with four through holes 103, and a nut 101 is fixed in each of the through holes 103. The screw hole on the nut 101 is equivalent to the first screw hole. Among them, see Figure 1 As shown ( Figure 1 The diagram shows the state where the cover plate 3 moves up a certain distance to expose the opening, and one end of the transport tank 5 extends out of the receiving cavity through the opening. The protective shell includes a shell 1, a receiving cavity and a cover plate 3. The receiving cavity is opened at the bottom of the shell 1 and extends through one of the two ends of the shell 1 to form an opening. The cover plate 3 is used to seal the opening. The protective shell also includes a fixing component for securing the cover plate 3 to the opening.

[0019] The fixing component includes a second screw hole 401, a through hole 402, and a bolt 4. The through hole 402 extends along the thickness direction of the cover plate 3. The second screw hole 401 is formed on the housing 1. The bolt 4 passes through the through hole 402 and is screwed into the second screw hole 401, so that the cover plate 3 abuts against the housing 1 to fix the cover plate 3 at the opening.

[0020] By adopting the above design, the cover plate 3 is fixed to the shell 1 with bolts 4, thereby sealing the cover plate 3 at the opening. This ensures that the front and rear ends of the transport tank 5 are in contact with the cover plate 3 and the end of the shell 1 away from the opening, respectively, which can prevent the protective shell from sliding back and forth during the transport process.

[0021] Among them, see Figure 1 and 3 As shown, the cover plate 3 includes a vertical plate 301 and a horizontal plate 302, which are perpendicular to each other. The through hole 402 is formed on the horizontal plate 302, and the second screw hole 401 is formed on the upper end of the housing 1. There are two through holes 402 and two screw holes 401. The two through holes 402 are respectively formed at both ends of the horizontal plate 302, and the two second screw holes 401 correspond one-to-one with the two through holes 402.

[0022] By adopting the above design, with the horizontal plate 302 attached to the top of the housing 1 and the vertical plate 301 attached to the side of the housing 1 at the opening, the phenomenon of the cover plate 3 rotating during use can be avoided, thus improving stability.

[0023] Furthermore, in this embodiment, a U-shaped slot 102 is provided at the lower end of the housing 1 at the opening. When the cover plate 3 blocks the opening, the lower end of the vertical plate 301 will be inserted into the slot 102, which further improves the stability of the blockage.
