Description

Technical Field

[0001] This utility model relates to the field of transportation auxiliary device technology, and in particular to an auxiliary tooling for the entry and exit of a power vehicle generator set in a vehicle compartment. Background Technology

[0002] A power supply vehicle, also known as a mobile power station, is a specialized piece of equipment that integrates a generator set onto a motor vehicle chassis. It is widely used in power outages, emergency power supply, field operations, and military support. Its core function is to provide a rapid, mobile, and independent power supply when the power grid cannot cover the area or in the event of a sudden power outage.

[0003] Currently, common power supply vehicles typically employ a closed, box-type structure. This structure offers advantages such as rainproofing, dustproofing, theft prevention, and sound insulation, protecting the internal generator set from external environmental damage. However, this closed structure also presents installation and maintenance challenges: the generator set, as the core component of the power supply vehicle, is enormous and typically weighs several tons. During initial installation or subsequent major overhauls, it must be moved entirely into or out of the vehicle. Existing technology primarily relies on large traction equipment combined with manual assistance, using the rear door of the vehicle for overall operation, which is laborious and inconvenient.

[0004] Therefore, there is an urgent need for an auxiliary device that enables heavy generator sets to be moved in and out of the enclosed compartment of a power vehicle conveniently, quickly, and safely. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide auxiliary tooling for the generator set of a power vehicle to enter and exit the vehicle compartment. By combining heavy-duty wheel sets and a mounting platform to replace the traditional traction method, the sliding friction at the bottom of the generator set is converted into rolling friction. Combined with a claw jack, the generator set can be conveniently and quickly moved in and out of the closed compartment of the power vehicle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An auxiliary tooling for a power vehicle generator set to enter and exit a vehicle compartment includes multiple heavy-duty wheel sets and an installation platform. The heavy-duty wheel sets are placed on the installation platform. Each heavy-duty wheel set includes multiple load-bearing wheels and a support plate. The support plate has multiple load-bearing wheels installed at its bottom and supports the generator set at its top.

[0008] As a preferred embodiment of auxiliary tooling for the entry and exit of generator sets in power vehicles, two of the aforementioned load-bearing wheels constitute a load-bearing wheel set, and multiple load-bearing wheel sets are evenly distributed along the length and width directions of the support plate.

[0009] As a preferred embodiment of auxiliary tooling for the entry and exit of the generator set of the power vehicle, adjacent load-bearing wheel sets arranged along the length direction of the support plate are connected by two first connecting plates; adjacent load-bearing wheel sets arranged along the width direction of the support plate are connected by a synchronous shaft; a second connecting plate is arranged above the first connecting plate along the width direction of the support plate, the second connecting plate is fixedly connected to the first connecting plate below and fixedly connected to the support plate above.

[0010] As a preferred embodiment of auxiliary tooling for the entry and exit of the generator set of a power vehicle, an intermediate bearing is provided between two of the load-bearing wheels in one load-bearing wheel set, and an end face bearing is provided through the center of the load-bearing wheel. The first connecting plate is clamped between the intermediate bearing and the end face bearing, and the synchronous shaft passes through the end face bearing, the intermediate bearing and the end face bearing of the other load-bearing wheel in the load-bearing wheel set in sequence.

[0011] As a preferred embodiment of auxiliary tooling for the entry and exit of generator sets in power vehicles, the installation platform is height-adjustable.

[0012] As a preferred auxiliary tooling solution for the entry and exit of the generator set of the power supply vehicle, claw jacks are also included.

[0013] The beneficial effects of this utility model are as follows:

[0014] This solution uses multiple heavy-duty wheel sets to convert the sliding friction at the bottom of the generator set into rolling friction, which greatly reduces the difficulty of the generator set entering and exiting the power supply vehicle. The entry and exit operations during generator set installation and overhaul can be completed by manual pushing and pulling combined with claw jacks. The device has a simple structure and is convenient and quick to operate. Attached Figure Description

Furthermore, the terms "first" and "second" are merely used for descriptive distinction and have no special meaning.

[0033] This embodiment provides an auxiliary tooling for the entry and exit of the generator set of a power supply vehicle into and out of the carriage, such as... Figure 1 As shown, the system includes multiple heavy-duty wheel sets 1 and a mounting platform 2. The heavy-duty wheel sets 1 are placed on the mounting platform 2. Each heavy-duty wheel set 1 includes multiple load-bearing wheels 101 and a support plate 102. The support plate 102 has multiple load-bearing wheels 101 mounted on its bottom and supports the generator set 3 on its top. Through the cooperation of the heavy-duty wheel sets 1 and the mounting platform 2, the sliding friction between the generator set 3 and the transport surface is converted into rolling friction, significantly reducing transport resistance. Figure 2 As shown, without the aid of large traction equipment, the generator set 3 can be easily and quickly pushed into the carriage 510 of the power vehicle 5 by manual labor.

[0034] Preferably, such as Figures 3 to 5 As shown, two load-bearing wheels 101 constitute a load-bearing wheel group. Multiple load-bearing wheel groups are evenly distributed along the length and width directions of the support plate 102. Adjacent load-bearing wheel groups arranged along the length direction of the support plate 102 are connected by two first connecting plates 103. Adjacent load-bearing wheel groups arranged along the width direction of the support plate 102 are connected by a synchronous shaft 104. A second connecting plate 105 is arranged above the first connecting plate 103 along the width direction of the support plate 102. The second connecting plate 105 is fixedly connected to the first connecting plate 103 below and fixedly connected to the support plate 102 above.

[0035] In this embodiment, each heavy-duty wheel set 1 includes four load-bearing wheel sets consisting of eight load-bearing wheels 101, and the support plate 102 is provided with two load-bearing wheel sets along the length direction and the width direction respectively.

[0036] Furthermore, an intermediate bearing 106 is provided between two load-bearing wheels 101 in a load-bearing wheel set, and an end-face bearing 107 is provided through the center of the load-bearing wheel 101. The first connecting plate 103 is clamped between the intermediate bearing 106 and the end-face bearing 107. The synchronous shaft 104 passes through the end-face bearing 107, the intermediate bearing 106, and the end-face bearing 107 of one load-bearing wheel 101 in a load-bearing wheel set in sequence. The mutual cooperation between the first connecting plate 103, the synchronous shaft 104, the second connecting plate 105, the intermediate bearing 106, and the end-face bearing 107 makes the heavy-duty wheel set 1 more stable and ensures that multiple load-bearing wheels 101 can move synchronously, preventing movement deviation. The generator set 3 is heavy, and if movement deviation occurs, it is difficult to correct.

[0037] Preferably, the height of the mounting platform 2 is adjustable to accommodate different models of power supply vehicles 5. The height of the lower end of the rear door 511 of the carriage is inconsistent with that of different models of power supply vehicles 5, so the height of the mounting platform 2 needs to be adjusted to ensure that the height of the mounting platform 2 is basically consistent with the height of the lower end of the rear door 511 of the carriage, so that the generator set 3 can be smoothly transported into and out of the carriage 510 via the heavy-duty wheel set 1.

[0038] Specifically, the height of the installation platform 2 can be adjusted by hydraulic lifting or electric lifting, or by placing a modular base under the bottom of the installation platform 2 in advance or by using multiple jacks. There are no restrictions on the height adjustment method of the installation platform 2, as long as the height of the installation platform 2 is basically the same as the height of the lower end of the rear door 511 of the carriage from the ground.

[0039] Preferably, the auxiliary tooling also includes a claw jack 4. The claw jack 4 is existing technology and readily available on the market; therefore, its structure will not be further described here. Figure 6 and Figure 7 As shown, the claw jack 4 can be inserted into the groove 301 on the side of the generator set 3. With the cooperation of multiple claw jacks 4, the generator set 3 can be lifted from multiple heavy wheel sets 1. At this time, all the heavy wheel sets 1 below are removed first, and then the generator set 3 is placed on the bottom of the carriage 510 through the claw jack 4. If the generator set 3 is to be transported out of the carriage 510, the above steps are reversed.

[0040] In practical applications, the transportation of generator set 3 specifically includes the following steps:

[0041] S1. Open the rear door 511 of the power supply vehicle 5 and use a gantry crane to lift the installation platform 2 to the rear door 511 of the vehicle.

[0042] S2. Adjust the height of the installation platform 2 to be basically the same as the height of the lower end of the rear door 511 of the carriage from the ground.

[0043] S3. Multiple heavy-duty wheel sets 1 are evenly arranged on the installation platform 2 along its length and width. In this embodiment, six heavy-duty wheel sets 1 are used, arranged in two columns along the length of the installation platform 2, with three heavy-duty wheel sets 1 in each column.

[0044] S4. The generator set 3 is hoisted and transported onto multiple heavy-duty wheel sets 1 using a gantry crane;

[0045] S5. Manually push the generator set 3 from the rear door 511 of the power vehicle 5 into the carriage 510. After reaching the appropriate position, use multiple claw jacks 4 to insert into the groove 301 on the side of the generator set 3 to lift the generator set 3 off the heavy wheel set 1.

[0046] S6. Remove all the heavy wheel sets 1 below, and then use the claw jack 4 to place the generator set 3 on the bottom of the carriage 510 to complete the transportation of the generator set 3. If you want to transport the generator set 3 out of the carriage 510, then reverse the above steps.
