Description

Technical Field

[0001] The present invention relates to the technical field of welding construction auxiliary equipment, and particularly to a movable welder's shed. Background Art

[0002] A welder's shed refers to a temporary work shed used by welders at the construction site, mainly for protecting from wind and rain, storing welding equipment, and providing a relatively safe working environment. The movable welder's shed is suitable for situations where the welding operation site needs to be flexibly adjusted, and is widely used in construction sites, shipyards, mechanical processing plants, etc. The current solution is to set rollers at the lower support end of the work shed for easy movement. In order to fix the work shed at the position where it is needed, a braking device is usually set on the rollers so that the rollers cannot rotate. Although it can prevent the work shed from moving to a certain extent, the firmness is poor. Under a large external force, it will still slide along the ground, causing inconvenience to the construction. In addition, in the prior art, usually one roller is set on each support column of the work shed, and the stability is poor. Although setting multiple rollers can improve the stability during fixation, multiple rollers will occupy a large space and are not conducive to moving in a narrow space. Summary of the Invention

[0003] In view of this, the embodiments of the present application provide a movable welder's shed for solving at least one of the above technical problems.

[0004] The technical solution adopted by the present invention is to design a movable welder's shed, which includes a support frame. The support frame includes support columns. A scissor deformation frame is provided at the bottom end of the support columns. The scissor deformation frame includes at least two scissors arranged up and down relative to the support columns. Each scissor includes two rod bodies. The middle parts of the two rod bodies are rotatably connected by a middle shaft hinge. The end parts of the rod bodies of the upper and lower scissors are rotatably connected by an end shaft hinge. The rotating shaft of one middle shaft hinge of the upper and lower scissors is connected to the support column, and the rotating shaft of the other middle shaft hinge is connected to a sleeve. The sleeve is slidably sleeved on the support column. The lower end part of the rod body of the lower scissor is connected to a roller.

[0005] In some embodiments, the rotating shaft of the middle shaft hinge of the upper scissor is connected to the support column, and the rotating shaft of the middle shaft hinge of the lower scissor is connected to the sleeve.

[0006] In some embodiments, insertion holes are arranged up and down on the support column, through holes corresponding to the insertion holes are arranged on the sleeve, and a pin that can be inserted into the insertion holes and the through holes at the same time is provided.

[0007] In some embodiments, the rotating shaft of the end shaft hinge is connected to the sliding sleeve, the end of the rod body is connected to the roller through a vertical rod, the roller is connected to the lower end of the vertical rod, the end of the rod body is rotatably connected to the vertical rod, the sliding sleeve is slidably sleeved on the vertical rod, and the vertical rod is parallel to the support column.

[0008] In some embodiments, a return spring is supported between the sleeve and the middle shaft hinge of the upper shear fork.

[0009] In some embodiments, the support frame further includes a top bracket supported between the upper ends of the two support columns. Guide wheels are provided at the upper ends of the two support columns. Both ends of a traction rope are respectively connected to the sleeves on the two support columns, and the traction rope simultaneously bypasses the guide wheels on the two support columns.

[0010] In some embodiments, a downward pull ring is provided in the middle of the traction rope between the two guides.

[0011] In some embodiments, the lower end of the support column is a conical tip.

[0012] In some embodiments, the rotating shaft of the middle shaft hinge of the lower shear fork is connected to the support column, and the rotating shaft of the middle shaft hinge of the upper shear fork is connected to the sleeve; the support frame further includes an upper top bracket supported between the upper ends of the two support columns.

[0013] In some embodiments, a lifting control device for controlling the lifting of the sleeve relative to the support column is provided on the support column.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a shear fork deformation frame between the support column and the roller. The shear fork deformation frame deforms as needed. When the shed is moving, the deformation frame is retracted, causing the end of the shed support column to rise, thereby reducing the bottom space occupied by the roller and facilitating rolling; when the shed is fixed, the deformation frame opens, causing the end of the shed support column to descend, which is beneficial for the end of the support column to support the ground for fixation. At this time, the roller is far from the support column, and a large support moment can be generated on the support column, thereby preventing the support column from tilting.

Detailed implementation manners

[0020] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following implementation manners do not limit the invention involved in the claims. In addition, all combinations of the features described in the implementation manners are not necessarily essential to the solution of the invention.

[0021] The principle and structure of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] First embodiment As Figure 1 、 2 shown, a movable welder's shed includes a rectangular support frame and a roof supported on the support frame, and the roof serves to protect from wind and rain.

[0023] The support frame includes four support columns 1 located at the four corners of the rectangle. The bottom ends of the support columns 1 are provided with scissor deformation frames. The scissor deformation frames include at least two scissors arranged up and down relative to the support columns 1. Each scissor includes two rod bodies 2, and the middle parts of the two rod bodies 2 are rotatably connected by a middle shaft hinge 4.

[0024] On one of the scissor deformation frames, the scissor located above is defined as the upper scissor, and the scissor located below is defined as the lower scissor. The end parts of the rod bodies 2 of the upper and lower scissors are rotatably connected by an end shaft hinge 3. The rotating shaft of one of the middle shaft hinges 4 of the upper and lower scissors is connected to the support column 1, and the rotating shaft of the other middle shaft hinge 4 is connected to the sleeve 5. The sleeve 5 is slidably sleeved on the support column 1. The lower end part of the rod body 2 of the lower scissor is connected to the roller 6. For simplicity, the upper end part of the rod body 2 of the upper scissor is close to the middle shaft hinge 4, that is, the rotating shaft of the middle shaft hinge of the upper scissor is arranged close to the upper end part of the rod body 2.

[0025] The rotating shaft of the middle shaft hinge 4 of the upper scissors in this embodiment is connected to the support column 1, and the rotating shaft of the middle shaft hinge 4 of the lower scissors is connected to the sleeve 5. The sleeve 5 plays a guiding role, enabling the middle shaft hinge 4 to slide up and down along the support column 1.

[0026] The support column 1 is provided with insertion holes 11 arranged vertically. The sleeve 5 is provided with through holes 51 corresponding to the insertion holes 11 and pins that can be inserted into the insertion holes 11 and the through holes 51 at the same time. When the pin is pulled out, the sleeve 5 can slide up and down relative to the support column 1, making the insertion holes 11 correspond to different through holes 51, and then inserting the pin, so that the sleeve 5 can be fixed at different positions. At this time, the two rod bodies 2 of the scissors cannot rotate relative to the middle shaft hinge 4, that is, the scissors deformation frame cannot deform.

[0027] The rotating shaft of the end shaft hinge 3 is connected to the sliding sleeve 7. The end of the rod body is connected to the roller 6 through the vertical rod 8. The roller 6 is connected to the lower end of the vertical rod 8. The end of the rod body 2 is rotatably connected to the vertical rod 8. The sliding sleeve 7 slides on the vertical rod 8. The vertical rod 8 is parallel to the support column 1. In this way, when the sleeve 5 moves up and down, no matter how the scissors deformation frame deforms and how the distance between the two vertical rods 8 changes, the two vertical rods 8 always remain parallel to the support column 1, so that the roller 6 stably supports symmetrically with respect to the support column 1. The two vertical rods 8 symmetrically support the support column 1 on both sides of the support column 1, which is beneficial to preventing the support column 1 from tilting.

[0028] A return spring 9 can be supported between the sleeve 5 and the middle shaft hinge 4 of the upper scissors. The return spring 9 is a cylindrical spring sleeved on the support column 1. When the pin leaves the insertion hole 11, the return spring 9 makes the support column 1 move upward relative to the sleeve 5, so that the lower end of the support column 1 is higher than the roller 6, so that the welder's shed only relies on the roller 6 to support on the ground at this time, facilitating the movement of the welder's shed by the rolling of the roller 6.

[0029] Furthermore, the lower end of the support column 1 is a conical tip to facilitate insertion into the ground.

[0030] Of course, a spacing adjustment mechanism can also be connected between the two vertical rods 8. The spacing adjustment mechanism can be, for example, a spacing adjustment bolt connected between the two vertical rods 8, and the distance between the two vertical rods 8 is adjusted by rotating the bolt.

[0031] Embodiment Two As Figure 3As shown, different from the above embodiments, the support frame further includes a top bracket 10 supported between the upper ends of the two support columns 1. The top bracket 10 can be used to carry a canopy to achieve the effect of wind and sun shading. Guide wheels 12 are provided at the upper ends of the two juxtaposed support columns 1. Both ends of a towing rope 13 are respectively connected to the sleeves 5 on the two support columns 1, and the towing rope 13 simultaneously bypasses the guide wheels 12 on the two support columns 1. A downward pull ring 14 is provided in the middle of the towing rope 13 between the two guides. In this way, by pulling down the middle of the towing rope 13 through the pull ring 14, the ends of the towing rope are simultaneously used to pull up the sleeve 5 upward, so that the sleeve 5 moves upward, causing the roller 6 to move away from the support column 1. At the same time, the downward force of the towing rope 13 acting on the guide wheel 12 causes the support column 1 to descend, so that the lower end of the support column 1 is inserted into the ground. When the support column 1 descends to an appropriate position, the sleeve 5 and the support column 1 are fixed by the bolt. When the support column 1 is inserted into the ground, the distance between the roller 6 and the support column 1 is relatively far, so that stable support can be provided for the support column 1. When the support column 1 leaves the ground upward, the distance between the two rollers 6 and the support column 1 is relatively close, which is equivalent to the scissor deformation frame being folded together, thereby reducing the occupied space and facilitating the movement of the welder's shed.

[0032] Embodiment III As Figure 4 shown, different from the above embodiments, the rotating shaft of the middle shaft hinge 4 of the lower scissor is connected to the support column 1, and the rotating shaft of the middle shaft hinge 4 of the upper scissor is connected to the sleeve 5. An elevation control device 16 for controlling the elevation of the sleeve 5 relative to the support column 1 is provided on the support column 1. The elevation of the sleeve 5 relative to the support column 1 is controlled to control the deformation of the scissor deformation frame, and then the auxiliary support or rolling of the roller 6 is realized. At this time, unnecessary structures such as the towing rope 13 and the bolt can be omitted.

[0033] The elevation control device 16 can be, for example, a pneumatic telescopic cylinder, a hydraulic telescopic cylinder, an electric cylinder or other telescopic mechanisms connected between the sleeve 5 and the support column 1. Of course, it can also be a manual telescopic adjustment mechanism. In short, it can realize the control of the movement of the sleeve 5 relative to the support column 1.

[0034] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
