Description

Technical Field

[0001] This invention relates to a triangular support positioning device for lowering cylindrical equipment to the ground, belonging to the field of mechanical design technology, and is applicable to the simultaneous ground contact requirements of multi-unit (8 or more rounds) cylindrical equipment. Background Technology

[0002] Existing special-operation vehicles carrying cylindrical equipment generate significant recoil and braking force on the cylinder during use. Currently, the main approaches to mitigate recoil and braking force on the cylinder are as follows:

[0003] a. Using multiple hydraulic cylinders to lower each cylindrical piece of equipment to the ground has the biggest problem that as the number of cylindrical pieces of equipment increases, the number of hydraulic cylinders will become enormous, causing huge problems for installation and use.

[0004] b. Using a single power source to connect a pallet to support the multi-unit cylindrical equipment and lower it to the ground, but as the number of cylindrical equipment increases further, the rigidity and strength design of the pallet will bring great difficulties.

[0005] c. Adding a grounding device to the tail of each cylindrical piece of equipment has the disadvantage of greatly increasing the complexity and cost of the cylindrical equipment.

[0006] d. Once the number of cylindrical equipment reaches a certain level, the equipment will no longer be distributed. The disadvantage is that it places higher demands on the rigidity and quality of the vehicles and affects the continuous and stable operation time. Summary of the Invention

Detailed Implementation

[0030] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0031] like Figures 1-6 The device shown is a triangular support positioning device for lowering cylindrical equipment to the ground, including a main frame 5 for connection and support and a column frame set on the upper surface of the main frame 5; one end of the main frame 5 is provided with a front connecting orienting device 1 for cylindrical equipment, and the main frame 5 is provided with a rear connecting orienting device 3 for cylindrical equipment; the column frame is provided with multiple triangular support mechanisms 2, and the bottom is provided with a roller group 4.

[0032] The cylindrical equipment is connected to the orientation device 3, which is located in the rear half of the main frame 5. The main frame 5 is welded from standard formed steel pipes.

[0033] The cylindrical equipment front connection orientation device 1 includes a front positioning frame connected to the main frame 5. Multiple first springs 11 are provided on the front positioning frame. Multiple first guide rails 13 corresponding to the positions of the first springs 11 are provided on the upper end surface of the front positioning frame. A wedge-shaped rotating pin 14 is provided at one end of the front positioning frame connected to the main frame 5.

[0034] The first guide rail 13 is provided with a first handle 12, and the rotating pin 14 is rotatably connected to the front positioning frame. The connection and release with the cylindrical equipment are achieved by rotating 90°.

[0035] The cylindrical equipment front connecting orientation device 1 is machined from high-strength steel, and the components are fixed by bolt connection.

[0036] Furthermore, each cylindrical equipment mounting position uses two rotatable wedge-shaped rotating pins 14. The rotating pins 14 switch between locked and unlocked states. In the transport state, all cylindrical equipment needs to be completely locked, but during the erection process, the forward degree of freedom of the cylindrical equipment needs to be released. To achieve this function, wedge-shaped rotating pins 14 are used. When the wedge direction is parallel to the direction of movement, the forward degree of freedom of the cylindrical equipment is released; when the wedge direction is perpendicular to the direction of movement, the forward degree of freedom of the cylindrical equipment is constrained.

[0037] The cylindrical equipment rear connection orientation device 3 includes a rear positioning frame connected to the main frame 5. Multiple second springs 31 are provided on the rear positioning frame, and multiple second guide rails 33 corresponding to the positions of the second springs 31 are provided on the upper end surface. A second rotation point 22 is provided on the second guide rails 33.

[0038] Specifically, the handle can limit the vertical movement of the cylindrical equipment, and the spring allows the handle to return to its original position after moving back and forth. The combination of spring and handle achieves both limiting and movement.

[0039] Furthermore, the spring ensures that the handle can move along with the cylindrical equipment and ensures the limit of the cylindrical equipment in other directions. The combination design of spring and handle is used on both sides of each cylindrical equipment installation position to ensure that the handle always constrains the upward degree of freedom of the cylindrical equipment during the forward and backward movement of the cylindrical equipment, that is, to restrict the degree of freedom of the cylindrical equipment in the vertical and horizontal directions.

[0040] Furthermore, two guide rails are used at each installation position of the cylindrical equipment to limit the left and right movement of the cylindrical equipment and guide it forward and backward, so as to meet the orientation requirements of the cylindrical equipment and restrict all degrees of freedom of the cylindrical equipment except for the forward direction of the axis and the vertical and horizontal directions upward.

[0041] Two layers of triangular support mechanisms 2 are provided on each of the left and right sides of the column frame, and the triangular support mechanisms 2 are connected by a linkage shaft 8.

[0042] The two triangular support mechanisms 2 on each side are driven by the same drive source. When the cylindrical equipment is being loaded, the entire crank-slider mechanism is in a retracted state. When the cylindrical equipment needs to be limited, the entire crank-slider mechanism is locked by the tail locking block 10.

[0043] The triangular support mechanism 2 is a crank-slider mechanism, which includes a column connected to the column frame. One end of the column is provided with a locking block 10, and one side of the column is provided with a positioning cross arm 6 and a support rod 7. One end of the positioning cross arm 6 and one end of the support rod 7 are connected to form a first turning point 21, the end of the positioning cross arm 6 connected to the column forms a second turning point 22, and the end of the support rod 7 connected to the column forms a third turning point 23.

[0044] The crank-slider mechanism is formed by welding of formed steel pipes and machining of steel plates. The other locking blocks 10 and guide rail grooves 24 are also machined from high-strength steel.

[0045] Specifically, when loading the cylindrical equipment, the locking block 10 is removed and the crank-slider mechanism retracts into the column frame; after the cylindrical equipment is loaded into place, the triangular support mechanism 2 unfolds and the locking block 10 is installed to complete the support of the cylindrical equipment.

[0046] Furthermore, since the cylindrical equipment is stacked in multiple layers, a foldable triangular support mechanism 2 is used to ensure that each layer of cylindrical equipment does not shift backward during erection. When loading the cylindrical equipment, the triangular support mechanism 2 is folded back into the column frame; after loading is completed, the triangular support mechanism 2 is unfolded to provide support.

[0047] The column has guide rail grooves 9 on both the left and right sides, and guide grooves 24 on both the top and bottom sides.

[0048] The roller assembly 4 consists of two sets of six rollers and one set of three rollers, machined from high-strength steel and heat-treated to increase its hardness, and is used for up-and-down movement.

[0049] Specifically, two sets of complete 6 rollers are used to complete the side limit of the entire device; a single set of 3 rollers on one side is used to complete the side limit of the entire device.

[0050] The advantages of this invention are:

[0051] 1. Instead of lowering the cylindrical equipment individually, the cylindrical equipment to be lowered is connected to this device as a whole and lowered together. At the same time, except for the forward direction, the other degrees of freedom of the cylindrical equipment and this device are released. After a single cylindrical piece of equipment lands, it can move forward relative to this device until all the cylindrical equipment lands, thus completing the lowering action.

[0052] 2. The mechanical structure enables the fixed connection of up to 12 cylindrical equipment units, meeting the requirement for independent lowering and landing of multi-unit cylindrical equipment. Simultaneously, once the entire invention slides down to meet the requirements for erecting the cylindrical equipment, the locking mechanism is released, allowing the cylindrical equipment to move upwards freely.

[0053] 3. It has the advantages of a single power source, simultaneous landing of multiple cylindrical equipment, adaptability to various slopes, and no mutual influence between the recoil and braking forces of the cylindrical equipment.
