Description

Technical Field

[0001] The present invention relates to the technical field of transportation equipment, and more particularly to an immersible self-propelled trolley device. Background Art

[0002] Offshore operations usually need to rely on a general assembly platform to complete the work. Generally, the weight of the general assembly platform is relatively large. At present, most of the launching methods use a module vehicle group to carry the platform onto a semi-submersible barge, and the semi-submersible barge dives and separates. However, due to the large volume and weight of the platform, a very large number of module vehicle groups are required. The cost of purchasing or renting module vehicles is very high. The existing longitudinal transfer trolleys adopt tracks that align the hull with the ground, and module vehicle groups are arranged on the tracks for transportation. However, due to the excessive length of the transportation group, the module vehicle group is mostly composed of multiple transport vehicles connected together. Each vehicle body is driven by its own motor respectively, and the motor cannot be disassembled, which is easily eroded by seawater and affects the service life. Therefore, when moving an object from land to the platform or barge by a transport vehicle, a support device needs to be additionally arranged under the object, and then the power vehicle group is made to leave the platform along the track and return to the land surface before the next step of work can be carried out. The efficiency is low, and an additional support device is required, and the support device is easily damaged and the cost is relatively high. Summary of the Invention

[0003] In summary, in order to overcome the deficiencies of the prior art, the present invention provides an immersible self-propelled trolley device.

[0004] To achieve the above object, the present invention provides the following technical solution: An immersible self-propelled trolley device, comprising two sets of symmetrically arranged motor car mechanisms, one end of the motor car mechanism is provided with a driving mechanism, the driving mechanism is detachably connected to the motor car mechanism, a jacking mechanism is arranged between the two sets of motor car mechanisms, the motor car mechanism includes an active single vehicle component and a driven single vehicle component, and a transmission component and a tensioning mechanism are arranged between the active single vehicle component and the driven single vehicle component.

[0005] By adopting the above technical solution, a jacking mechanism is arranged between the two sets of motor car mechanisms for supporting the platform. Only a driving mechanism is arranged at one end of the motor car mechanism. Compared with the prior art that uses a module vehicle group composed of multiple module vehicles, the cost is greatly reduced. At the same time, the driving mechanism is detachably connected to the motor car mechanism. Compared with the module vehicle that cannot disassemble its respective driving mechanism, after the platform is carried onto the semi-submersible barge by the motor car mechanism in this technical solution, the driving mechanism is disassembled, and the motor car mechanism can support the platform and dive with the semi-submersible barge, without the need for an additional support device and the process of making the power vehicle group leave the platform along the track and return to the land surface, reducing the support and fixation cost and greatly improving the work efficiency.

[0006] The present invention is further provided that: one end of the active bicycle assembly corresponding to the driving mechanism is provided with a driving shaft, and the other end is provided with a driven shaft. One side of the driving shaft is provided with a driving wheel, and the other side is provided with a driven wheel. One end of the driven shaft corresponding to the driven wheel is provided with a sprocket adapted to the driven wheel, and the other end is provided with a small gear. The active bicycle assembly includes two wheel shafts, which are arranged between the driving shaft and the driven shaft. Wheels and large gears are arranged on the wheel shafts. The large gears are arranged at one end of the wheel shafts corresponding to the small gears and are meshed with the small gears.

[0007] By adopting the above technical solution, the driving wheel drives the driven wheel to rotate through the driving shaft, the driven wheel drives the driven shaft to rotate through the sprocket, the driven shaft drives the large gear through the small gear, and the large gear drives the wheel to rotate. Through the cooperation of the sprocket, the small gear and the large gear, the transmission assembly rotates synchronously with the wheel. By using one driving mechanism to realize the operation of two mechanisms, the structure is simplified, the cost is reduced, and the efficiency is high.

[0008] The present invention is further provided that: the driving mechanism includes a motor and a speed reducer. The motor is arranged at one end of the speed reducer. The speed reducer is detachably arranged on the active bicycle assembly. One side of the speed reducer corresponding to the driving wheel is provided with a driving wheel for driving the driving wheel, and the driving wheel is matched with the driving wheel.

[0009] By adopting the above technical solution, by setting the speed reducer to control the driving mechanism to automatically move forward or backward along the track, the operation is simpler and more convenient. The driving wheel is driven by the motor to drive the driving wheel to rotate. The structure is simple and the efficiency is high.

[0010] The present invention is further provided that: one end of the active bicycle assembly corresponding to the speed reducer is provided with a mounting part. The speed reducer is mounted on the mounting part and is bolted to the active bicycle assembly.

[0011] By adopting the above technical solution, through the mounting part, there is a gap between the speed reducer and the deck, and it is not easily eroded by the seawater on the deck. At the same time, through the bolt connection between the speed reducer and the mounting part, it is convenient to disassemble, and the operation is simple and labor-saving.

[0012] The present invention is further provided that: the driven bicycle assembly includes two driven shafts and two wheel shafts. The wheel shafts are arranged between the driven shafts. One end of each driven shaft is provided with a sprocket, and the sprockets are in transmission cooperation through a chain. The other end of each driven shaft is provided with a small gear. Wheels and large gears are arranged on the wheel shafts. The large gears are arranged at one end of the wheel shafts corresponding to the small gears and are meshed with the small gears.

[0013] By adopting the above technical solution, through the coordination of the sprocket, the small gear and the large gear, the driven bicycle components or the driven bicycle components and the active bicycle components can rotate synchronously, with high stability and high efficiency. The operation of the wheels can be achieved through a driving mechanism while the coordination between the bicycle components can be achieved, which simplifies the structure, reduces costs and improves efficiency.

[0014] The present invention is further provided that: the tensioning mechanism includes a tensioning wheel arranged on the upper and lower sides of the chain and an adjusting component for adjusting the tensioning wheel, the adjusting component includes a clamping piece and an adjusting piece, the motor vehicle mechanism is provided with a mounting frame for fixing the clamping piece, and a hinged shaft hinged to the motor vehicle mechanism is provided in the middle of the clamping piece, one end of which is connected to the tensioning wheel, and the other end is connected to the mounting frame through the adjusting piece.

[0015] By adopting the above technical solution, a tensioning wheel is provided to make the cooperation between the chain and the sprocket more stable. The spacing between the mounting frame and the clamping member is changed by the adjusting member, thereby changing the rotation angle of the clamping member, thereby adjusting the spacing between the tensioning wheels on the upper and lower sides of the chain. This technical solution can adopt adjustable tensioning (i.e., setting a tensioning wheel and an adjusting component) or non-adjustable tensioning (only a single tensioning wheel) according to needs.

[0016] The present invention is further provided that: the jacking mechanism comprises an oil cylinder, and the oil cylinder is arranged in the middle of the wheel axle.

[0017] By adopting the above technical solution, an oil cylinder is set up, which has high pressure resistance and stability. It is set in the middle of the wheel axle, that is, between the two side motor vehicles and in the center of the single vehicle assembly, so that the single vehicle assembly is balanced in force and runs stably.

[0018] The present invention further provides that: a matching wheel assembly is arranged behind the driven bicycle assembly, the number of the driven bicycle assembly is n, n is an integer greater than or equal to 1, and the number of the matching wheel assemblies is not greater than 3 (n+1).
