Description

Technical Field

[0001] The utility model relates to the technical field of sand and gravel conveying equipment for water conservancy and hydropower dams, in particular to a width and slope regulating device for a belt conveyor transmission system. Background Art

[0002] Currently, a belt conveyor (e.g., a belt conveyor) is typically used to transport materials such as sand and gravel, and concrete mixed with the sand and gravel is poured into the dam formwork to form a dam. The dam has functions such as flood control and power generation.

[0003] In the existing technology, the bandwidth of the belt conveyor (i.e., the width of the steel structure truss) usually needs to be set and adjusted in time according to the transmission distance and transmission volume of sand and gravel. The slope of the belt conveyor (i.e., the angle between the steel structure truss and the ground) usually also needs to be set and adjusted in time according to the terrain conditions of the dam.

[0004] For example, when adjusting the width of a steel structure truss (e.g., making it wider), first, the steel structure truss is lifted using a lifting device, and then the columns arranged below the steel structure truss are moved to both sides until the columns are moved to the ends of the steel structure truss. For another example, when adjusting the slope of a steel structure truss (e.g., making the slope higher), first, the steel structure truss is lifted using a lifting device, and then columns of the required height are added to the upper surface of the columns arranged below the steel structure truss (i.e., new columns). Finally, the steel structure truss is placed on the upper surface of the new columns using the lifting device.

[0005] However, adjusting the width and slope of the steel trusses using the above method requires first lifting the steel trusses using a lifting device, then going through a series of intermediate steps, and finally lowering the steel trusses using the lifting device. In other words, adjusting the width and slope of the steel trusses using the above-mentioned lifting device (i.e., the lifting device) is cumbersome and labor-intensive.

[0006] Therefore, there is an urgent need for a width adaptation and slope adjustment device for a steel structure truss, which can not only achieve width adaptation and slope adjustment of the steel structure truss, but also has a simple structure and can simplify the adjustment steps. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides a width and slope adjustment device for a belt conveyor transmission system, which can not only achieve width adaptation and slope adjustment of the steel structure truss, but also has a simple structure and can simplify the adjustment steps.

[0008] The utility model provides a width and slope adjustment device for a belt conveyor transmission system, which is characterized by comprising: an adaptation adjustment mechanism arranged between the steel structure truss and the column for adapting the width of the steel structure truss and adjusting the slope of the steel structure truss;

[0009] The adaption and adjustment mechanism includes a width adaption mechanism provided above the column for adapting the width of the steel structure truss, and a slope adjustment mechanism provided above the width adaption mechanism for adjusting the slope of the steel structure truss;

[0010] The width adaptation mechanism includes a U-shaped groove, and a first support plate for sliding arranged in the U-shaped groove and adapted to the U-shaped groove;

[0011] The slope adjustment mechanism includes an outer sleeve fixedly arranged above the first support plate for adjusting the slope of the steel structure truss, an inner sleeve clamped in the outer sleeve, and a limiting mechanism arranged at the junction of the outer sleeve and the inner sleeve for fixing the overlapping length between the outer sleeve and the inner sleeve;

[0012] The inner wall of the outer sleeve is provided with three sliding grooves equally divided by 120 degrees from each other, and the outer wall of the inner sleeve is provided with a plurality of sliding blocks adapted to the sliding grooves;

[0013] The limiting mechanism includes a first limiting component arranged between the sliders for initially fixing the overlapping length between the outer sleeve and the inner sleeve, and the thickness of the first limiting component is smaller than the distance between two adjacent sliders.

[0014] The above-mentioned width and slope adjustment device for a belt conveyor transmission system is characterized in that: the limiting mechanism also includes a second limiting component arranged below the first limiting component and fixedly connected to the first limiting component for secondary fixing the overlapping length between the outer sleeve and the inner sleeve, the inner wall of the second limiting component includes an annular groove, and an annular limiting ball adapted to the annular groove is fixedly provided on the outer wall of the outer sleeve.

[0015] The above-mentioned width and slope adjustment device for a belt conveyor transmission system is characterized in that it also includes a second support plate fixedly arranged on the upper surface of the inner sleeve and used to abut against the steel structure truss.

[0016] The beneficial effect reasoning analysis is as follows:

[0017] In the prior art, adjusting the width and slope of a steel truss requires first lifting the truss using a lifting device, then going through a series of intermediate steps before finally lowering it back down using the lifting device. This means that adjusting the width and slope of the steel truss (i.e., the lifting device) requires complex and labor-intensive steps.

[0018] The technical solution of the present invention, firstly, by moving the first support plate in the U-shaped groove, the outer sleeve and the inner sleeve fixed above the first support plate move synchronously, thereby adapting the column position to the width of the steel structure truss, avoiding the existing situation in which a series of complicated operations such as lifting equipment are required to achieve the column position matching the width of the steel structure truss, which consumes a lot of manpower. Secondly, by moving the inner sleeve (for example, upward or downward), and finally using a limit mechanism to fix the relative position of the inner sleeve and the outer sleeve, the slope of the steel structure truss is adjusted, avoiding the existing situation in which a series of operations such as lifting equipment and adding new columns are required to achieve the steel structure truss slope adjustment, which consumes a lot of manpower.

[0019] Therefore, the width adaptation and slope adjustment device for the steel structure truss of the present invention can not only achieve the width adaptation and slope adjustment of the steel structure truss, but also has a simple structure, simplifies the adjustment steps, and saves manpower.

[0030] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the scope of the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention, that is, the features of the embodiments, can be combined with each other. The present invention will be described in detail below with reference to the embodiments and in conjunction with the accompanying drawings.

[0032] In the prior art, adjusting the width and slope of a steel truss requires first lifting the truss using a lifting device, then going through a series of intermediate steps before finally lowering the truss using the lifting device. This means that the adjustment steps for the steel truss width and slope adjustment device (i.e., the lifting device) are cumbersome.

[0033] Based on this, the utility model provides a width and slope adjustment device for a belt conveyor transmission system, which can not only make the columns match the width of the steel structure truss, but also adjust the slope of the steel structure truss (that is, the angle between the steel structure truss and the ground).

[0034] Figure 1 This is a longitudinal sectional view of a belt conveyor transmission system including a steel structure truss and columns provided by the utility model. Figure 2 To set in Figure 1 Schematic diagram of the three-dimensional structure of the width and slope adjustment device for the belt conveyor transmission system between the steel structure trusses and columns. Figure 3 for Figure 2 The schematic diagram of the structure of the outer sleeve with an annular limiting ball is provided. Figure 4 for Figure 2 Schematic diagram of the structure of the middle limit mechanism, Figure 5 for Figure 2 Schematic diagram of the cross-sectional structure of the limiting mechanism at the junction of the outer sleeve and the inner sleeve.

[0035] See also Figure 1 , Figure 1 The hypotenuse of the middle triangle is a steel structure truss, the short right-angled sides of the triangle are columns, and the columns are arranged in pairs and at intervals below the two ends of the steel structure truss.

[0036] Combine Figures 2 to 4 The utility model provides a width and slope adjustment device for a belt conveyor transmission system, comprising: an adaptation adjustment mechanism arranged between a steel structure truss and a column for adapting the width of the steel structure truss and adjusting the slope of the steel structure truss;

[0037] The adaption and adjustment mechanism includes a width adaption mechanism arranged above the column for adapting the width of the steel structure truss, and a slope adjustment mechanism arranged above the width adaption mechanism for adjusting the slope of the steel structure truss;

[0038] The width adaptation mechanism includes a U-shaped groove 1, a first support plate 2 for sliding arranged in the U-shaped groove 1 and adapted to the U-shaped groove;

[0039] The slope adjustment mechanism includes an outer sleeve 3 fixedly arranged above the first support plate 2 for adjusting the slope of the steel structure truss, an inner sleeve 4 clamped in the outer sleeve 3, and a limiting mechanism 12 arranged at the junction of the outer sleeve 3 and the inner sleeve 4 for limiting the relative length between the outer sleeve 3 and the inner sleeve 4;

[0040] The inner wall of the outer sleeve 3 is provided with three sliding grooves 5 equally divided by 120 degrees from each other, and the outer wall of the inner sleeve 4 is provided with a plurality of sliders 6 adapted to the sliding grooves 5;

[0041] The limiting mechanism 12 includes a first limiting assembly 7 disposed between the sliders 6 for initially limiting the relative length between the outer sleeve 3 and the inner sleeve 4 .

[0042] The U-shaped groove 1 has a certain extension length, the first support plate 2 can slide in the U-shaped groove, and the outer sleeve 3 fixedly connected to the first support plate 2 can slide synchronously.

[0043] When the total length between the outer sleeve 3 and the inner sleeve 4, or in other words, the overlapping length between the outer sleeve 3 and the inner sleeve 4 reaches the expected value, the limiting mechanism 12 (specifically the first limiting component 7) arranged between the outer sleeve 3 and the inner sleeve 4 can fix the above two at the junction between the two, so that the relative position between the above two is fixed.

[0044] For specific implementation, see Figure 1 When the width of the steel structure truss becomes wider, the outer sleeve 3 can be directly slid and pushed, and a pair of first support plates 2 fixed at the bottom of the outer sleeve 3 can slide synchronously. When the first support plates 2 slide to the position below the two ends of the steel structure truss, they stop sliding.

[0045] Continue to see Figure 1 When the slope of the steel structure truss needs to be increased, the inner sleeve 4 can be pushed upward directly. When it is pushed to a certain length, the limiting mechanism 12 (specifically the first limiting component 7) is rotated (i.e., pushed horizontally) so that the first limiting component 7 is located between the upper and lower adjacent sliders 6 to prevent the inner sleeve 4 from sliding downward.

[0046] The beneficial effect reasoning analysis is as follows:

[0047] In the prior art, adjusting the width and slope of a steel truss requires first lifting the truss using a lifting device, then going through a series of intermediate steps before finally lowering it back down using the lifting device. This means that adjusting the width and slope of the steel truss (i.e., the lifting device) requires complex and labor-intensive steps.

[0048] In the technical solution of the present invention, firstly, the first support plate 2 is moved in the U-shaped groove 1, so that the outer sleeve 3 and the inner sleeve 4 fixed above the first support plate 2 move synchronously, thereby achieving the adaptation of the column position to the width of the steel structure truss, avoiding the situation in the prior art where a series of complicated operations of lifting equipment are required to achieve the column position matching the width of the steel structure truss, which consumes a lot of manpower. Secondly, by moving the inner sleeve 4 (for example, upward or downward), and finally using the limit mechanism 12 to fix the relative position of the inner sleeve 4 and the outer sleeve 3, the slope of the steel structure truss is adjusted, avoiding the situation in the prior art where a series of operations such as lifting equipment and adding new columns are required to achieve the slope adjustment of the steel structure truss, which consumes a lot of manpower.

[0049] Therefore, the width adaptation and slope adjustment device for the steel structure truss of the present invention can not only achieve the width adaptation and slope adjustment of the steel structure truss, but also has a simple structure, simplifies the adjustment steps, and saves manpower.

[0050] In the embodiment described above, a width adaption and slope adjustment device for a steel structure truss is introduced. In another embodiment of the present invention, other components for performing a second reinforcement on the junction of the outer sleeve 3 and the inner sleeve 4 are introduced.

[0051] For example, the limiting mechanism 12 also includes a second limiting component 8 arranged below the first limiting component 7 and fixedly connected to the first limiting component 7 for secondary fixing the overlapping length between the outer sleeve 3 and the inner sleeve 4. The inner wall of the second limiting component 8 includes an annular groove 9, and an annular limiting ball 10 adapted to the annular groove 9 is fixedly arranged on the outer wall of the outer sleeve 3.

[0052] The annular groove 9 and the annular limiting ball 10 cooperate with each other to achieve secondary fixation of the secondary relative positions of the inner and outer sleeves.

[0053] In a specific implementation, first, a circle of annular limiting balls 10 can be set on the outer wall of the upper end of the outer sleeve 3.

[0054] Second, before the first limiting assembly 7 is installed to the junction of the inner and outer sleeves, the second limiting assembly 8 (including the annular groove 9) is fixedly connected below the first limiting assembly 7.

[0055] Third, a first stopper assembly 7 and a second stopper assembly 8 are integrally connected and pass downward from the top of the inner sleeve 4. It is understood that the diameter of the outer sleeve 3 is larger than that of the inner sleeve 4, so the diameter of the second stopper assembly 8 in contact with the outer sleeve 3 is larger than the diameter of the first stopper assembly 7 in contact with the inner sleeve 4 (see for details).

[0056] Fourth, rotate (i.e. push in the lateral or horizontal direction) the first limit component 7 so that the first limit component 7 can be clamped between the two upper and lower adjacent sliders 6. At the same time, a circle of annular limit balls 10 arranged on the outer wall of the outer sleeve 3 is clamped in the second limit component 8 (specifically annular groove 9) arranged below the first limit component 7 and fixedly connected to the first limit component 7, thereby achieving two fixations at the junction of the inner and outer sleeves, that is, fixing the relative lengths of the inner and outer sleeves, that is, making the slope of the steel structure truss stable after the slope is adjusted.

[0057] In the above-mentioned embodiment, other components are introduced for the second reinforcement of the junction between the outer sleeve 3 and the inner sleeve 4. In another embodiment of the present invention, a support plate is introduced which is arranged above the inner sleeve 4 and is used to abut against the steel structure truss.

[0058] For example, it further includes a second support plate 11 fixedly arranged on the upper surface of the inner sleeve 4 for abutting against the steel structure truss.

[0059] The second support plate 11 can be fixed on the upper end of the inner sleeve 4 .

[0060] In a specific implementation, the steel structure truss can be lifted by a lifting device, and then the inner sleeve 4 is stretched upward and the first limit assembly 7 is rotated. Finally, the lifting device presses the steel structure truss against the second support plate 11 to complete the adjustment of the slope of the steel structure truss.

[0061] Preferably, when the inner sleeve 4 is pulled upward, the inner sleeve 4 can be pulled upward manually, or a rotating handle can be provided on the outer surface of the limiting mechanism 12 to move the inner sleeve 4 upward by rotating the handle.

[0062] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
