Description

Technical Field

[0001] This invention relates to the field of truck structure technology, and specifically proposes a fixing device for mining truck bodies. Background Technology

[0002] Mining truck bodies are specialized cargo-carrying devices mounted on heavy-duty mining dump trucks, used for loading and transporting materials such as ore and coal. They are core components of core transportation equipment in mines. Mining trucks, as large transport equipment, are extremely heavy and generally only suitable for driving on mining area roads. Driving on ordinary roads would damage the surface, so mining trucks are often transported in disassembled units. Mining truck bodies, as integral cargo-carrying devices, can be transported independently. For short-distance transfers, mining truck bodies are often transported using powered flatbed trucks, typically two powered flatbed trucks connected in series. Additionally, limit frames and multiple support platforms are installed on the two powered flatbed trucks. The mining truck body can be placed entirely on these support platforms and simply restrained by the limit frames. However, existing mining truck body transportation equipment has the following shortcomings.

[0003] 1. The support platform and the limiting frame can only provide simple support and simple limiting functions, respectively. They do not effectively constrain and fix the mining truck body. When accelerating, turning, or braking suddenly, or when encountering bumpy roads or surrounding obstacles, the transportation stability of the mining truck body will be greatly reduced, and there is a risk of the mining truck body sliding or overturning.

[0004] 2. If two powered flatbed trucks are connected in series and the powered flatbed trucks cannot turn independently, the turning radius will be too large, affecting the flexibility of transportation operations, especially when passing through narrow areas. If they can turn independently, relative slippage will inevitably occur between the support platform and the truck bed when turning, which greatly increases the risk of transportation.

[0005] Mining trucks are large in size, which inevitably creates blind spots during transportation operations. The instability of the transportation equipment and the various risks involved not only increase the resistance to smooth transportation but also pose potential safety risks to personnel in the work area.

On multiple support beams; each set of fixing assemblies consists of two units, and the two fixing assemblies are symmetrically arranged along the length of the support beam; the fixing assembly includes a base fixed on the support beam and a support platform fixed on the top of the base for supporting the bottom of the mining truck body; two opposing longitudinal clamping plates are horizontally slidably installed on both sides of the support platform, and a side clamping assembly is provided on the side of the support platform, which is located between the two longitudinal clamping plates.

Under the drive of the drive assembly, the side clamping assembly is clamped to the outer side wall of the mining truck body, and the longitudinal clamping plates are clamped to the side wall of the crossbeam at the bottom of the mining truck body.

[0008] Preferably, the sliding hinge block includes a first slider and a second slider distributed vertically, with the first slider and the second slider in a vertical rotational engagement; the first slider is in a sliding engagement with the support beam, and the second slider is in a sliding engagement with the longitudinal rail.

[0009] Preferably, the drive assembly includes a drive shaft that is slidably mounted on the bottom of the support platform along its length and a slide plate that is fixed to the drive shaft. The slide plate is slidably mounted on the bottom of the support platform, and multiple connecting rods are hinged between the two longitudinal clamping plates and the slide plate.

[0010] Preferably, the side clamp assembly includes a side clamp plate fixed to one end of the drive shaft.

[0011] Preferably, the side of the side clamping plate facing away from the side clamping surface is provided with a guide rail, a sliding member is slidably installed in the guide rail, a side support rod is hinged to the sliding member, and the side support rod is also hinged to the base.

[0012] Preferably, when the two flatbed trailers do not deflect or turn relative to each other, the support beam is perpendicular to the longitudinal rail.

[0015] Preferably, the support frame is H-shaped, and the center of the bottom end of the support frame is fixed to the hinge axis of the hinge hook.

At the same time, the two flatbed trailers still retain the function of independent steering. The rigid connection of the mining truck carriages does not restrict steering, and the mining truck carriages will not slip relative to the supporting platform due to steering. This reduces the turning radius, achieves the purpose of flexible steering, and avoids the risk of lateral tilting and slippage during steering.

[0019] 3. In summary, the fixing device for mining truck carriages provided by the present invention, as a mining truck carriage transportation equipment with fixing and constraint function, strengthens the fixing and clamping constraint of the mining truck carriage to improve the stability and safety of transportation. At the same time, it realizes stable and flexible steering; overall, it enhances the smoothness of transportation operations and improves safety. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a fixing device for a mining truck body 9 includes two flatbed trailers 1 connected in series by hinge hooks 11, a support base frame 2 mounted on the two flatbed trailers 1, and multiple fixing assemblies 3 mounted on the support base frame 2 for cooperating to support and fix the mining truck body 9; as shown Figure 2 The image shows a mining truck body 9 of a certain model. In order to ensure structural strength, meet the requirements of long service life, and facilitate the setting of fixing points for assembly with the mining truck body, two longitudinal beams 91 and five transverse beams 92 are welded to the bottom of the mining truck body 9. The five transverse beams 92 have the same width and are evenly distributed in the longitudinal direction.

[0035] It should be noted that the articulated hook 11 is an existing trailer connection device (including articulated pin) that can realize articulated connection. The two flatbed trailers 1 are connected in series through the articulated hook 11, which has the basis for relative deflection and steering. In addition, the flatbed trailers 1 are existing remotely controlled electric flatbed trailers. When traveling in the forward and backward directions, the two flatbed trailers 1 can be controlled and switched as active vehicles and passive vehicles respectively.

[0036] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the supporting base 2 includes a support frame 21 with an H-shaped welded frame structure. The support frame 21 includes two side beams and a crossbeam, with the crossbeam centrally welded between the two side beams. A connecting frame 211 is centrally welded to the bottom of the crossbeam, and the crossbeam is welded to the top of the hinge shaft of the hinge hook 11 via the connecting frame 211. Six support beams 22 are horizontally fixed between the two side beams by bolts. The six support beams 22 are evenly distributed, with three on each side of the crossbeam. Five sliding hinge blocks 23 are horizontally slidably installed at the bottom of each support beam 22. The six support beams 22 are divided into two groups corresponding to the two flatbed trailers 1, and each flatbed trailer 1 is fixed with bolts. Five longitudinal rails 12 are centrally located and evenly distributed along the width of the flatbed trailer 1, and extend along its length. Each support beam 22 is slidably mounted on one of the five longitudinal rails 12 on the corresponding flatbed trailer 1 via five sliding hinge blocks 23. Each sliding hinge block 23 includes a first slider 231 and a second slider 232 distributed vertically. A rotating shaft is vertically mounted between the first slider 231 and the second slider 232, and both sliders 231 and 232 are vertically rotatable with the rotating shaft via bearings. The first slider 231 is slidably engaged with the support beam 22, and the second slider 232 is slidably engaged with the longitudinal rail 12. When the two flatbed trailers 1 are not turning relative to each other, the support beam 22 is perpendicular to the longitudinal rail 12.

[0037] like Figure 1 , Figure 4 , Figure 8 and Figure 10 As shown, each support beam 22 is equipped with a set of fixing assemblies 3. There are two fixing assemblies 3 in each set. The two fixing assemblies 3 are symmetrically arranged in the length direction of the support beam 22 and are installed close to both ends of the support beam 22. The fixing assembly 3 includes a base 4 and a support platform 5 fixed to the top of the base 4 and used to support the bottom of the mining truck body 9. The base 4 is inserted and installed on the support beam 22 and is fixed and locked by bolts. A slide rail 51 is centrally located at the bottom of the support platform 5 in the width direction, and the slide rail 51 is along the length direction of the support platform 5. Multiple slide grooves 52 are evenly distributed along the length direction of the support platform 5 on both sides of the slide rail 51 at the bottom of the support platform 5, and the slide grooves 52 on both sides of the slide rail 51 are arranged opposite to each other. The slide grooves 52 and the slide rail 51 are perpendicular to each other. Two longitudinal clamping plates 6 are symmetrically arranged on both sides of the slide rail 51 on the support platform 5. Multiple sliding parts 61 are welded on the side of the longitudinal clamping plate 6 facing away from the clamping surface. The longitudinal clamping plate 6 is slidably installed in multiple slide grooves 52 on the same side of the slide rail 51 through multiple sliding parts 61. Multiple inclined grooves for improving friction are opened on the clamping surface of the longitudinal clamping plate 6.

[0038] like Figure 8 and Figure 9 As shown, a side clamping assembly 7 is provided on the side of the support platform 5. The side clamping assembly 7 is located between two longitudinal clamping plates (6). The support platform 5 is also equipped with a drive assembly 8 for synchronously driving the side clamping assembly 7 and the two longitudinal clamping plates 6. The drive assembly 8 includes an electric hydraulic cylinder 81 that is horizontally fixed to the bottom of the support platform 5 by bolts. The output end of the electric hydraulic cylinder 81 is fixedly connected to a drive shaft 82 by bolts. The drive shaft 82 is horizontally slidably installed in the slide rail 51. A slide plate 83 is fixed to the drive shaft 82 by screws. The slide plate 83 slides in cooperation with the slide rail 51. Multiple sliding parts 6 of the two longitudinal clamping plates 6 A connecting rod 84 is hinged to both the 1 and the slide plate 83. The side clamping assembly 7 includes a side clamping plate 71 welded to one end of the drive shaft 82 through a fixed sleeve. A guide rail 711 is provided on the side of the side clamping plate 71 facing away from the side clamping surface. A sliding member 72 is slidably installed in the guide rail 711. A tension spring 73 is installed in the guide rail 711, and the two ends of the tension spring 73 are welded to the side clamping plate 71 and the sliding member 72 respectively. A side support rod 74 is hinged to the sliding member 72. The side support rod 74 is also hinged to the base 4. The side support rod 74 strengthens the lateral support of the side clamping plate 71 to improve the overall side clamping strength of the side clamping plate 71.

[0039] When transporting the mining truck body 9, it can be stably lifted using a gantry crane or other hoist. The flatbed trailer 1 is remotely controlled to move directly beneath the mining truck body 9. The hoisting position is then fine-tuned by the crane to ensure the five crossbeams 92 and six sets of fixed assemblies 3 are evenly spaced. The mining truck body 9 is then placed smoothly on the six sets of support platforms 5, with each crossbeam 92 positioned between two adjacent sets of fixed assemblies 3, and the area between two fixed assemblies 3 in each set avoiding contact with two longitudinal beams 91. Next, all the electric hydraulic cylinders 81 are activated, causing their output ends to retract. This drives the drive shaft 82 to bring the side clamps 71 closer to and tightly press against the mining truck body 9. On the outer side wall, when the side clamping plate 71 moves, the sliding member 72 slides adaptively, and the side support rod 74 provides lateral auxiliary support. On the other hand, the drive shaft 82 drives the slide plate 83 to slide, and the slide plate 83 drives the two longitudinal clamping plates 6 to be clamped on the side walls of the crossbeams 92 on both sides through two sets of connecting rods 84. Thus, the fixed constraint of the mine truck body 9 is completed by the six sets of fixing assemblies 3. It should be noted that only one longitudinal clamping plate 6 of the fixing assembly 3 on both sides is clamped on the crossbeam 92, but it also plays the role of fixed constraint. When performing the fixed clamping constraint operation, the mine truck body 9 can be slightly lifted to facilitate the adaptive adjustment of the attitude of the mine truck body 9 during the fixed constraint.

[0040] Compared with the existing transportation equipment that simply supports and limits the placement of the mining truck carriages 9, in this invention, multiple sets of fixing assemblies 3, in addition to supporting the mining truck carriages 9, can further perform multiple longitudinal clamping on the multiple sets of crossbeams 92 and multiple sets of lateral clamping on the side walls of the mining truck carriages 9, so as to provide active multiple fixing and clamping constraints, thereby improving the stability and reliability of transportation under various driving conditions, various road surfaces and environmental conditions, avoiding slippage and tilting, and greatly reducing transportation risks.

[0041] Furthermore, the support base 2 is fixed only to the hinge shaft of the hinge hook 11. The two flatbed trailers 1 are connected to the support base 2 through multiple sets of sliding hinge blocks 23, ensuring the basic support connection between the support base 2 and the two flatbed trailers 1. At the same time, when the mining truck body 9 is placed on the multiple sets of fixed assemblies 3 and the fixed clamping constraint is completed, the mining truck body 9 forms a rigid series connection between the fixed assemblies 3 distributed with the two flatbed trailers 1. However, the two flatbed trailers 1 still retain the function of independent steering. When steering, one flatbed trailer 1 As the active vehicle, another flatbed trailer 1 acts as the driven vehicle. Multiple fixed assemblies 3 can still maintain a stable and fixed constraint on the mining truck body 9. During the rotation process, the first slider 231 can adaptively slide along the support beam 22, while the second slider 232 can adaptively slide along the longitudinal rail 12. The rigid connection of the mining truck body 9 does not restrict the steering, and the mining truck body 9 will not slip relative to the support platform 5 due to steering. This reduces the turning radius, achieves the purpose of flexible steering, and avoids the risk of tilting and slipping during steering.
