Technical Field
[0001] This application belongs to the field of engineering machinery technology, and specifically relates to a trailer pump traction device. Background Technology
[0002] Concrete trailer pumps are widely used in concrete pumping operations in construction, tunneling, and other engineering projects. Due to the frequent switching between construction sites and road transport, they are typically towed by a tractor. However, existing concrete trailer pump towing devices generally use fixed-height towing hooks or ball joints, making them incompatible with different tractor heights. Furthermore, the coupling methods are limited, and changing the coupling is time-consuming. Therefore, there is an urgent need for a towing device that combines height adjustment and quick coupling to improve the safety and adaptability of concrete trailer pumps during road travel and operational condition switching. Summary of the Invention
[0003] The purpose of this application is to provide a trailer pump traction device to solve the problems of the inability to adjust the height of the traction head and the single form of the traction device, which makes it unable to adapt to tractors of different heights.
[0004] To achieve the above objectives, this application provides a trailer pump traction device, comprising: The towing beam is connected to the front end of the trailer pump; The connection module has an adjustable height position on the traction beam. The connection module includes a housing, a locking and limiting component, and multiple hook-up components. The multiple hook-up components extend from the traction beam and are arranged at intervals along the height direction. The hook-up components are located on the side of the housing away from the trailer pump and are used to hook up with the tractor. The locking and limiting component is used to lock and limit the housing and the traction beam at a preset height.
[0005] In some embodiments, the box body includes a box body and two first limiting blocks disposed on the box body and spaced apart in the horizontal direction. Each first limiting block extends in a first direction. The traction beam has two sliding grooves extending in the height direction. The first limiting blocks and the sliding grooves are slidably inserted into each other. The first direction is perpendicular to both the horizontal direction and the height direction.
[0006] In some embodiments, the locking and limiting assembly is located between the two first limiting blocks and includes: Mounting base; A clamping block is provided between each of the first limiting blocks on both sides of the mounting base along the horizontal direction. One side of the clamping block is limited and abutted against the first limiting block, and the other side is engaged with the wedge-shaped surface of the mounting base. A locking element is used to lock the mounting base, the traction beam, and the housing.
[0007] In some embodiments, the traction beam is provided with a plurality of mounting holes spaced apart along the height direction for the locking member to pass through, and the plurality of mounting holes are located between two of the sliding grooves.
[0008] In some embodiments, the traction beam is a hollow structure with an open side facing away from the trailer pump. The hook-up assembly extends outward from the open side of the traction beam. The hook-up assembly includes a sleeve and a hook ring. The sleeve is detachably connected to the side wall of the box body. The hook ring is located on the side of the sleeve facing away from the box body and is used to hook up with the tractor.
[0009] In some embodiments, the mounting assembly further includes a connecting rod, which is inserted into the sleeve and used to lock the sleeve and the box body together. A vibration damping elastic element and a shearing flexible element are coaxially sleeved on the connecting rod, and the vibration damping elastic element and the shearing flexible element are arranged sequentially in a direction away from the box body.
[0010] In some embodiments, the hook assembly further includes a ball head connected between the sleeve and the hook ring.
[0011] In some embodiments, the two sides of the traction beam arranged parallel to each other along a first direction are a first wall and a second wall, respectively. The box body is located inside the traction beam and includes a first mounting surface and a second mounting surface arranged parallel to each other along the first direction, as well as a side surface connecting the first mounting surface and the second mounting surface. The first limiting block is disposed on the first mounting surface and extends out of the slide groove. The second mounting surface and the second wall are arranged at intervals. The locking member locks the first wall, the first mounting surface, the second mounting surface and the second wall in sequence along the first direction.
[0012] In some embodiments, the locking and limiting assembly further includes a second limiting block, which is connected between the second mounting surface and the second wall surface and sleeved on the outer periphery of the locking member.

[0014] Through the above technical solution, the towing beam is connected to the front end of the trailer pump; the height position of the connecting module on the towing beam is adjustable. The connecting module includes a housing, a locking and limiting component, and multiple hook-up components. These hook-up components extend from the towing beam and are spaced apart along the height direction, making the hook-up methods more diverse and adaptable to the hook-up requirements of different types of tractor vehicles. The hook-up components are located on the side of the housing facing away from the trailer pump and are used to hook up with the tractor vehicle. The locking and limiting component is used to lock and limit the housing and the towing beam at a preset height. The height position of the connecting module on the towing beam in this application is adjustable, thus changing the overall height of the connecting module. When towing with tractor vehicles of different heights, only the height position of the connecting module needs to be adjusted, thereby adapting to hook-up with tractor vehicles of different heights.

[0017] Explanation of reference numerals in the attached figures Detailed Implementation
[0018] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0019] The trailer pump traction device according to this application is described below with reference to the accompanying drawings.
[0020] like Figure 1As shown, this application proposes a trailer pump traction device, including a traction beam 10 and a connecting module; the traction beam 10 is connected to the main beam 50 of the frame at the front end of the trailer pump; the height position of the connecting module on the traction beam 10 is adjustable, and the connecting module includes a housing 20, a locking and limiting component 30 and multiple hooking components 40. The multiple hooking components 40 extend from the traction beam 10 and are arranged at intervals along the height direction. The hooking components 40 are located on the side of the housing 20 away from the trailer pump and are used to hook with the tractor vehicle. The locking and limiting component 30 is used to lock and limit the housing 20 and the traction beam 10 at a preset height.
[0021] This application provides multiple mounting components 40 along the height direction on the housing 20, making the mounting methods more diverse and adaptable to the mounting requirements of different types of tractor vehicles. Furthermore, the height position of the connecting module on the towing beam 10 is adjustable, thus changing the overall height of the connecting module. When towing tractor vehicles of different heights, only the height position of the connecting module needs to be adjusted, thereby adapting to the mounting requirements of tractor vehicles of different heights. Moreover, the entire trailer pump towing device adopts a modular layout, the mounting components 40 are replaceable, the structure is simpler, and maintenance efficiency is improved.
[0022] In some embodiments, the box body 20 includes a box body 21 and two first limiting blocks 22 disposed on the box body 21 and spaced apart in the horizontal direction. Each first limiting block 22 extends in a first direction. The traction beam 10 has two sliding grooves 11 extending in the height direction. The first limiting blocks 22 and the sliding grooves 11 are slidably inserted into each other in a one-to-one correspondence. The first direction is perpendicular to both the horizontal direction and the height direction.
[0023] The first direction is Figure 1 The front-to-back direction is defined by the front-to-back direction, the horizontal direction by the left-to-right direction, and the vertical direction by the height direction. Each first limiting block 22 extends along the front-to-back direction and slides vertically into the corresponding slide groove 11. When the first limiting block 22 slides along the slide groove 11 in the vertical direction, the height of the entire box body 21 can be changed to accommodate tractors of different heights.
[0024] In some embodiments, the locking and limiting assembly 30 is located between two first limiting blocks 22 and includes a mounting base 31, a clamping block 32, and a locking member 33; a clamping block 32 is provided between each of the two sides of the mounting base 31 in the horizontal direction and each of the first limiting blocks 22, one side of the clamping block 32 is limited and abutted against the first limiting block 22, and the other side is engaged with the wedge-shaped surface of the mounting base 31; the locking member 33 passes through the mounting base 31, the traction beam 10 and the housing 20 in sequence in the first direction and locks them.
[0025] like Figure 1 and Figure 2As shown, the mounting base 31 has a plum blossom-shaped structure with a wedge-shaped surface on its outer periphery. The clamping block 32 has a flat surface facing the first limiting block 22 and fits against the first limiting block 22. The side facing away from the first limiting block 22 has a wedge-shaped surface that mates with the side surface 25 of the mounting base 31. Thus, the clamping block 32 and the mounting base 31 are fixed by the wedge-shaped surface engagement. Of course, other similar wedge-shaped block clamping and fixing methods are also within the scope of protection of this application. Furthermore, after the locking member 33 locks the mounting base 31 and the traction beam 10, the mounting base 31 and the clamping blocks 32 on both sides clamp and fix the first limiting block 22 of the housing 20 by the wedge-shaped surface engagement, and provide frictional force in the horizontal and vertical directions to the first limiting blocks 22 on both sides, thereby forming a "shear bolt + wedge-shaped block surface pressure" dual-bearing type, improving the structural strength.
[0026] In some embodiments, the traction beam 10 is provided with a plurality of mounting holes 12 for the locking member 33 to pass through at intervals along the height direction, and the plurality of mounting holes 12 are located between two slide grooves 11.
[0027] In this embodiment, multiple mounting holes 12 are arranged in a row in the height direction, and the sliding grooves 11 on both sides are symmetrically arranged about the row of mounting holes 12 in the middle. When it is necessary to change the height of the box 20, the locking member 33 can be removed to move the entire box 20 up or down. When the mounting hole 12 corresponding to the preset position is reached, the locking member 33 passes through the mounting hole 12 to lock the mounting base 31, the traction beam 10 and the box 20. This structure can realize the step lifting of the entire box 20 through the vertical mounting holes 12 to meet the needs of tractor vehicles of different heights.
[0028] In some embodiments, the towing beam 10 is a hollow structure with an open side facing away from the trailer pump. The hook-up assembly 40 extends outward from the open side of the towing beam 10. The hook-up assembly 40 includes a sleeve 41 and a hook ring 42. The sleeve 41 is detachably connected to the side wall of the box body 21. The hook ring 42 is located on the side of the sleeve 41 facing away from the box body 21 and is used to hook up with the tractor.
[0029] In this embodiment, one side wall of the box body 21 is located at the opening of the traction beam 10, and one end of the sleeve 41 is located at the opening. The sleeve 41 and the side wall of the box body 21 are detachably connected by bolts to facilitate the replacement of the hook assembly 40. The end of the hook ring 42 away from the sleeve 41 has a hooking part for hooking with the tractor, and the other end of the hook ring 42 is detachably connected to the sleeve 41. In this application, the number of hook assemblies 40 is at least two sets, or more than two sets. By changing the different structural forms of the hook rings 42 of different hook assemblies 40, different types of tractor hooking requirements can be adapted. For example, the hook ring 42 can be set as a hook or a hook connector.
[0030] like Figure 5 As shown, the mounting assembly 40 also includes a connecting rod 46, which is inserted into the sleeve 41 and used to lock the sleeve 41 and the box body 21. A vibration damping elastic element 43 and a shearing flexible element 44 are coaxially sleeved on the connecting rod 46. The inner peripheral walls of the vibration damping elastic element 43 and the shearing flexible element 44 are in contact with the connecting rod 46, and the outer peripheral walls are in contact with the sleeve 41. The vibration damping elastic element 43 and the shearing flexible element 44 are arranged sequentially in the direction away from the box body 21.
[0031] In this design, the damping elastic element 43 is a damping spring, and the shearing flexible element 44 is shear rubber. When the towing system experiences slight yaw or pitch, the shear rubber provides damping, reducing the impact of towing swaying and braking pitch, and improving straight-line and lane-changing stability. When the towing system experiences sudden stops and accelerations, the damping spring provides compressible and stretchable flexibility to suppress transient impacts. Of course, in other embodiments, other similar coaxial damping methods can also be used, all of which are within the scope of protection of this application.
[0032] like Figure 4 As shown, the mounting assembly 40 also includes a ball head 45 connected between the sleeve 41 and the hanging ring 42. By setting the ball head 45, the connection stability between the sleeve 41 and the hanging ring 42 can be improved.
[0033] like Figure 2 and Figure 3 As shown, the traction beam 10 has two parallel and spaced sides arranged along a first direction, namely a first wall surface 13 and a second wall surface 14. A side wall surface connects the first wall surface 13 and the second wall surface 14, and the other side opposite to the side wall surface is open. The box body 21 is located inside the traction beam 10 and includes a first mounting surface 23 and a second mounting surface 24 arranged parallel and spaced along a first direction, as well as a side surface 25 connecting the first mounting surface 23 and the second mounting surface 24. A first limiting block 22 is provided on the first mounting surface 23 and extends out of the slide groove 11. The second mounting surface 24 and the second wall surface 14 are arranged at intervals. The locking member 33 locks the first wall surface 13, the first mounting surface 23, the second mounting surface 24 and the second wall surface 14 in sequence along the first direction. In this embodiment, the top of the first mounting surface 23 and the side of the first wall surface 13 facing the second wall surface 14 are attached. The first wall surface 13 has a through hole for the first limiting block 22 to pass through. When adjusting the height of the entire connecting module, the locking member 33 is unlocked, and the first limiting block 22 is manually applied to slide along the slide groove 11. When it slides to the preset height, the locking member 33 locks the first wall surface 13, the first mounting surface 23, the second mounting surface 24 and the second wall surface 14, thereby realizing the height adjustment of the entire connecting module.
[0034] In some embodiments, the locking and limiting assembly 30 further includes a second limiting block 34, which is connected between the second mounting surface 24 and the second wall surface 14 and sleeved on the outer periphery of the locking member 33. The presence of the second limiting block 34 limits the position of the locking member 33, preventing positional displacement during the locking and limiting process. Furthermore, for better limiting, both sides of the second limiting block 34 are respectively fitted to the second mounting surface 24 and the second wall surface 14.
[0035] In some embodiments, the locking member 33 includes a rod portion and a locking portion. The rod portion extends in a front-rear direction and sequentially passes through the mounting base 31, the mounting hole 12, the first wall surface 13, the first mounting surface 23, the second mounting surface 24, and the second wall surface 14. The locking portion is threadedly locked to the end of the rod portion. The outer periphery of the rod portion is provided with external threads. The locking portion engages with the external threads of the rod portion to lock the rod portion and the second wall surface 14 together. Of course, in other embodiments, the fastener can also be other structural forms that can achieve locking, and is not limited to the bolt and screw structure mentioned in the embodiments of this application.
