Abstract
Description
Technical Field
[0001] The utility model relates to the field of bus production, and particularly relates to a bus roof lifting tooling. Background Art
[0002] A bus, that is, a bus or a coach, is a typical model of large and medium-sized buses in the passenger car category, and is a commercial vehicle designed and equipped specifically for solving urban and suburban transportation.
[0003] Currently, common buses are generally 6 - 12 meters long. Their roofs are heavy and the center of gravity is unstable. In the prior art, lifting tools such as lifting ropes are generally used to lift the roof to the roof for installation. This is not only time-consuming and laborious, but also there are situations where the roof is prone to tipping and falling off, posing a certain safety hazard. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies existing in the prior art, and provide a bus roof lifting tooling, which increases the stress area during lifting, makes the center of gravity of the roof more stable, and is not easy to shake and tip.
[0005] The purpose of the utility model is completed through the following technical solutions: This bus roof lifting tooling includes a tooling body and a roof. A skylight is penetrated and opened on the roof. The tooling body includes a main beam, a lifting hook arranged on the top of the main beam, and an ear arranged on the side wall of the main beam. A side beam is arranged above the ear, and a nut is welded at the bottom of the ear for connecting a T-shaped screw rod. A roof frame is arranged on the lower surface of the roof; during lifting, the main beam is placed under the skylight, and the lifting hook extends from above the skylight for connecting a lifting device. The T-shaped screw rod passes through the side beam, the skylight, and the ear in sequence and is locked with the nut, so that the side beam presses against the upper surface of the roof, and at the same time, the main beam and the ear both abut against the roof frame, realizing the clamping and fixing of the tooling body and the roof.
[0006] As a further technical solution, there are two ears, which are symmetrically welded on the main beam.
[0007] As a further technical solution, connection brackets are arranged between both sides of the lifting hook and the main beam to form a triangular support structure.
[0008] As a further technical solution, the length of the roof is 10 - 12m, and a skylight is symmetrically opened on both sides of the roof, and a tooling body is correspondingly installed in each skylight.
[0009] As a further technical solution, the length of the roof is 6 - 8m, and a skylight is opened on one side of the roof, and a sling is connected to the other side of the roof.
[0010] The beneficial effects of the utility model are as follows:
[0011] 1. The tooling body clamps the side beam and the lug (main beam) up and down on the top cover by rotating the T-shaped screw rod, making the center of gravity more stable, less likely to slip during hoisting, and having higher hoisting efficiency.
[0012] 2. After the main beam, side beam and top cover are clamped, a surface contact is formed, increasing the stress area and enhancing the hoisting reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Description of the reference numerals: Tooling body 1, main beam 11, hook 12, lug 13, side beam 14, nut 15, T-shaped screw rod 16, connecting bracket 17, top cover 2, skylight 21, top cover frame 22. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The following will introduce the present utility model in detail with reference to the drawings:
[0023] Embodiment 1: As shown in the Figures 1 to 8 drawing, this bus top cover hoisting tooling includes a tooling body 1, a main beam 11, a hook 12, a lug 13, a side beam 14, a nut 15, a T-shaped screw rod 16, a connecting bracket 17, a top cover 2, a skylight 21 and a top cover frame 22.
[0024] Taking the top cover 2 of a bus with a length of 10 - 12 m as an example, as Figure 3, 5 As shown in Figure 6, a skylight 21 is symmetrically opened on both sides of the top cover 2, and a tooling body 1 is correspondingly installed in each skylight 21, so that the two tooling bodies 1 are also symmetrical, the center of gravity is more stable, it is not easy to slip during hoisting, and the hoisting efficiency is higher.
[0025] Refer to the appendix Figure 1 , 2 , the tooling body 1 includes a main beam 11, and a hook 12 is welded and fixed on the top of the main beam 11. Preferably, connecting brackets 17 are arranged between both sides of the hook 12 and the main beam 11 to form a triangular support structure.
[0026] Furthermore, two lugs 13 are symmetrically welded on the side wall of the main beam 11, a side beam 14 is arranged above the lugs 13, a nut 15 is welded and fixed at the bottom of each lug 13, and through holes are opened at the positions corresponding to the nut 15 on the lugs 13 and the side beam 14 for the T-shaped screw 16 to pass through.
[0027] As Figures 5 to 8 shown, a top cover frame 22 (welded and fixed to the top cover 2) is arranged on the lower surface of the top cover 2. During hoisting, the main beam 11 is placed below the skylight 21, and the hook 12 extends out from above the skylight 21, which is convenient for the hook 12 to connect the hoisting equipment. By rotating the T-shaped screw 16 to pass through the side beam 14, the skylight 21 and the lug 13 in sequence and then locking it with the nut 15, the side beam 14 is pressed against the upper surface of the top cover 2, and at the same time, the main beam 11 and the lugs 13 are both abutted against the top cover frame 22, realizing the clamping and fixing of the tooling body 1 and the top cover 2 up and down. Preferably, the nut 15 adopts a GB-6170 (10-grade) M14 high-strength nut.
[0028] Preferably, the main beam is made of Q235 square pipe, and the side beam 14 and the lugs 13 are made of Q235 square pipe cut open and welded firmly by CO2 shielded welding. The thickness of the electrophoretic paint on the outer surface of the tooling body 1 is about 30μm, and the thickness of the surface paint is about 50μm.
[0029] Embodiment 2: The difference from Embodiment 1 is that for the top cover 2 of a bus with a length of 6-8m, due to the length, only one skylight 21 is opened on one side of the top cover 2, and a tooling body 1 is correspondingly installed. The other side of the top cover 2 is still fixed to the cross beam by a sling for hoisting. Compared with the existing technology where the sling installation is completely adopted, the presence of the tooling body 1 greatly enhances the stability.
[0030] Working process of the utility model: The utility model utilizes the skylight 21 on the top cover 2 to place the tooling body 1 into the skylight 21. At the same time, rotate the T-shaped screw rod 16 to gradually clamp the upper and lower surfaces of the top cover 2 by the side beam 14 and the support ear 13 (main beam 11), so as to realize the upper and lower clamping and fixing of the tooling body 1 and the top cover 2. During hoisting, since the hook 12 passes through the skylight 21, the tooling body 1 and the top cover 2 can be directly lifted by a lifting device, and the hoisting center of gravity is more stable, and it is not easy to tip over or slip off.
[0031] It can be understood that for those skilled in the art, any equivalent replacement or change to the technical solution and the inventive concept of the present utility model should fall within the protection scope of the appended claims of the present utility model.
