[0002] Long-distance belt conveyors are mostly used for transporting ores between mines and factory areas. There are many mountainous areas along the line, and the terrain fluctuates greatly. The required support heights are not uniform. Moreover, because long-distance belt conveyors are often several kilometers long, the design workload of supports is huge. For traditional inverted-V supports, each support with a different height needs to be designed separately to adapt to different height requirements, resulting in a complex variety of materials and high production and management costs. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an adjustable-height inverted-V support, which adapts to complex terrain through height adjustment and solves the problem of different-height supports required for long-distance belt conveyors.

[0004] The purpose of the utility model is achieved by the following technical solutions: An adjustable-height inverted-V support includes a support shoulder beam, a top steel pipe, and a support main body. A convex plate is provided on the support shoulder beam. A steel pipe end plate is provided at the top of the top steel pipe. An end plate cover is provided on the top of the steel pipe end plate and is combined with the steel pipe end plate to form a slider. The slider is matched with the convex plate and can move along the convex plate. The bottom of the top steel pipe is inserted into the support main body, and a bottom collar is further sleeved on the bottom of the top steel pipe. A collar is provided at the top of the support main body, and a clamping plate is provided on the collar. A constraint is formed between the bottom collar and the collar to ensure that the steel pipes of the top steel pipe and the support main body are concentric. A limiting collar can also be sleeved on the upper part of the top steel pipe.

[0005] The end plate cover and the steel pipe end plate are combined into a "匚"-shaped structure and sleeved on the convex plate, which is convenient for the end plate cover and the steel pipe end plate to clamp the convex plate for sliding.

[0006] The top steel pipe includes a left top steel pipe and a right top steel pipe. Left and right openings are provided at the top of the support main body. The bottom of the left top steel pipe is inserted into the left opening, and the bottom of the right top steel pipe is inserted into the right opening. The left top steel pipe and the right top steel pipe form a shape similar to an inverted V.

[0007] The steel pipe end plate includes a left steel pipe end plate and a right steel pipe end plate. The end plate cover plate includes a left end plate cover plate and a right end plate cover plate. The left steel pipe end plate is disposed on the top of the left top steel pipe, and the right steel pipe end plate is disposed on the top of the right top steel pipe. The left end plate cover plate is disposed on the left steel pipe end plate, and the right end plate cover plate is disposed on the right steel pipe end plate. The left end plate cover plate and the left steel pipe end plate are combined to form a left slider, and the right end plate cover plate and the right steel pipe end plate are combined to form a right slider. Both the left slider and the right slider are engaged with a convex plate and can move along the convex plate.

[0008] The bottom collar includes a left bottom collar and a right bottom collar. The collar includes a left collar and a right collar. The clamping plate includes a left clamping plate and a right clamping plate. The left bottom collar is set at the bottom of the left top steel pipe, and the right bottom collar is set at the bottom of the right top steel pipe. It is used to fill the gap between the left top steel pipe and the left opening, and between the right top steel pipe and the right opening, to ensure the concentricity of the left top steel pipe and the left opening, and between the right top steel pipe and the right opening. The left collar is set at the top of the left opening, and the right collar is set at the top of the right opening. It is used to constrain the concentricity of the left top steel pipe and the left opening, and between the right top steel pipe and the right opening. The left clamping plate is set on the left collar, and the right clamping plate is set on the right collar.

[0009] The left clamping plate includes a first half-clamping plate and a second half-clamping plate that cooperate with each other, and the right clamping plate includes a third half-clamping plate and a fourth half-clamping plate that cooperate with each other. The first half-clamping plate is fixedly connected to the left collar, and the third half-clamping plate is fixedly connected to the right collar. The first half-clamping plate and the second half-clamping plate, as well as the third half-clamping plate and the fourth half-clamping plate, are all fixed with bolts. When the bolts are loosened, the top steel pipe can be freely adjusted in position; when the bolts are tightened, the top steel pipe is locked.

[0010] The end plate cover is fixed to the steel pipe end plate by bolts.

[0011] The support beam is also equipped with a shoulder pad. The main body of the support is a fixed, non-adjustable structure. There are two main pipes in a figure-eight shape on the left and right sides. The bottom of the main pipes has bolt holes and is fixed to the ground by pre-embedded bolts. A horizontal pipe is welded between the two main pipes to fix them into a whole and improve the structural stability.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model allows for adjustment of the position of the top steel pipe inserted into the main body of the support column by loosening the clamping plate bolts. At the same time, the position of the end plate cover and the steel pipe end plate on the support column shoulder beam can be adjusted by sliding, so that the support column shoulder beam can move vertically up and down to achieve the purpose of adjusting the height of the support column.

[0014] 2. When the top steel pipe is inserted into the main body of the support column, the end plate cover and the steel pipe end plate slide outwards towards the shoulder beam of the support column, causing the column height to decrease; when the top steel pipe is pulled out of the main body of the support column, the end plate cover and the steel pipe end plate slide inwards towards the shoulder beam of the support column, causing the column height to increase. After adjusting to the appropriate height, tighten the clamp bolts and perform a trial assembly of the support column. After the trial assembly is successful, weld the positions where the support column shoulder beam contacts the top steel pipe, and the positions where the top steel pipe contacts the main body of the support column, to enhance the load-bearing capacity and durability of the support column.

[0015] 3. This utility model limits the top steel pipe by the cooperation of the collar and the bottom collar, keeping it coaxial with the main body of the support column, and allowing it to slide freely in the main body. Attached Figure Description

[0024] In the first embodiment of the present application:

[0025] An adjustable-height inverted-V-shaped support column includes a support column shoulder beam 1, a top steel pipe 5, and a support column main body 9. The support column shoulder beam 1 is mainly composed of an H-shaped steel. There is a convex plate provided on the support column shoulder beam 1. A steel pipe end plate 3 is provided at the top of the top steel pipe 5. The steel pipe end plate 3 is in an "L" shape. An end plate cover plate 2 is provided at the topmost part of the steel pipe end plate 3 and combines with the steel pipe end plate 3 to form a slider (that is, the steel pipe end plate 3 and the end plate cover plate 2 cooperate to form a "匚"-shaped clip for clamping the convex plate). The slider clamps the convex plate and can move along the convex plate. The bottom of the top steel pipe 5 is inserted into the support column main body 9, and a bottom collar 8 is also sleeved on the bottom of the top steel pipe 5. A collar 7 is welded to the top of the support column main body 9, and a half clamping plate 6 is welded to the collar 7. When the staff adjusts the top steel pipe 5 to the specified height, the bolt group 4 is used to fix the other half of the clamping plate to this half clamping plate 6. When installing and using the adjustable-height inverted-V-shaped support column, first loosen the bolt group 4 of the clamping plate 6 so that the top steel pipe 5 can freely slide up and down in the support column main body 9. Pull out the top steel pipe 5 outward, and the top steel pipe 5 drives the support column shoulder beam 1 to move up, increasing the overall height of the support column; insert the top steel pipe 5 inward, and the overall height of the support column decreases. After adjusting to the target height, the other half of the clamping plate and the half clamping plate 6 on the collar 7 are locked by the bolt group 4 to achieve fixation. Then, the support column is trial-mounted to ensure that the height is correct. After confirming that the height of the support column is correct, the contact surfaces between the support column shoulder beam 1 and the end plate cover plate 2 and the steel pipe end plate 3 are fully welded, and the contact surfaces between the collar 7 and the top steel pipe 5 and the clamping plate 6 are fully welded. After the welding is completed, the welded joints are polished and painted. The support column is fixedly installed by using embedded bolts through the bolt holes at the bottom of the support column main body 9.

[0026] A steel plate is welded at the position of the shoulder pad installed at the upper end of the support column shoulder beam 1, and bolt holes are drilled in cooperation with it for installing the shoulder pad.

[0027] In the second embodiment of the present application:

[0028] As Figures 1 to 5 shown, on the basis of the previous embodiment, this embodiment makes improvements to the top steel pipe 5 and the support column main body 9. The top steel pipe 5 includes a left top steel pipe and a right top steel pipe. The support column main body 9 is in the shape of a letter "A". Left and right openings are respectively provided at the left and right ends of the top of the support column main body 9. The bottom of the left top steel pipe is inserted into the left opening, and the bottom of the right top steel pipe is inserted into the right opening.

[0029] The steel pipe end plate 3 includes a left steel pipe end plate and a right steel pipe end plate, and the end plate cover plate 2 includes a left end plate cover plate and a right end plate cover plate. The top of both the left and right top steel pipes are provided with slots. The left steel pipe end plate is set at the top slot of the left top steel pipe and welded. A collar 7 is welded to the upper part of the left and right top steel pipes, and then another collar 7 is fitted on the outside of the collar 7. The right steel pipe end plate is set at the top slot of the right top steel pipe and welded. The left end plate cover plate is set on the left steel pipe end plate, and the right end plate cover plate is set on the right steel pipe end plate. The left end plate cover plate and the left steel pipe end plate are combined to form a left slider, and the right end plate cover plate and the right steel pipe end plate are combined to form a right slider. Both the left and right sliders cooperate with the convex plate and can move along the convex plate.

[0030] The bottom collar 8 includes a left bottom collar and a right bottom collar, the collar 7 includes a left collar and a right collar, the clamping plate 6 includes a left clamping plate and a right clamping plate, the left bottom collar is welded to the bottom of the left top steel pipe, the right bottom collar is welded to the bottom of the right top steel pipe, the left collar is set at the top of the left opening, the right collar is set at the top of the right opening, the left clamping plate is set on the left collar, and the right clamping plate is set on the right collar.

[0033] The end plate cover 2 and the steel pipe end plate 3 are fixed by bolt group 4. When installing and using the adjustable height figure-eight support, first loosen the bolts between the first half clamp plate and the second half clamp plate, and between the third half clamp plate and the fourth half clamp plate, so that the left top steel pipe and the right top steel pipe can slide freely up and down within the support body 9. When the left top steel pipe and the right top steel pipe are pulled outward, the left top steel pipe and the right top steel pipe drive the support shoulder beam 1 to move upward, and the left slider and the right slider slide inward along the convex plate and move closer to each other, increasing the overall height of the support. When the left top steel pipe and the right top steel pipe are pushed inward, the left slider and the right slider slide outward along the convex plate and move away from each other, decreasing the overall height of the support. After adjusting to the target height, the first half-clamp plate and the second half-clamp plate, as well as the third half-clamp plate and the fourth half-clamp plate, are all locked with bolts to achieve fixation. Then, the support column is trial-assembled to ensure that the height is correct. After confirming that the support column height is correct, the contact surfaces between the support column shoulder beam 1 and the end plate cover plate 2 and the steel pipe end plate 3 are fully welded. Each collar 7 is fully welded to the contact surfaces between the top steel pipe 5, the clamp plate 6, and the collar 7. After welding, the welded areas are ground and painted. The support column is then fixed and installed using pre-embedded bolts through the bolt holes at the bottom of the support column body 9.
