DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-4 As shown, the present invention provides a technical solution: a nuclear power emergency diesel generator set traction mobile equipment, including a traction base unit, the traction base unit is composed of two traction auxiliary bases 1, one end of the traction base unit is against the diesel generator set outlet side of the plant base 3, and two parallel traction rails 11 are arranged on the traction auxiliary base 1, and the traction rails 11 match the base rails 31 on the plant base 3.

[0033] The traction auxiliary base 1 is a convex frame, and a buffer rubber pad 12 is fixed to the tail end of the traction auxiliary base 1. The buffer rubber pad 12 faces the factory base 3, which can prevent the traction auxiliary base 1 from directly contacting the factory base 3 and improve the service life of the traction auxiliary base 1.

[0034] The side of the traction auxiliary base 1 is provided with a weight reduction hole 13, which reduces the overall mass of the traction auxiliary base 1 and facilitates the operator to move and use the traction auxiliary base 1. A reinforcing pad 14 is fixed at the bottom end of the traction auxiliary base 1.

[0035] Two auxiliary connecting plates 4 are rotatably connected to both sides of the front end of the traction auxiliary base 1, and the connection between two adjacent traction auxiliary bases 1 is completed through the auxiliary connecting plates 4, so as to facilitate the assembly of the traction base unit. When performing traction movement over a longer distance, the number of traction auxiliary bases 1 can be increased to increase the length of the traction auxiliary unit, and the traction auxiliary base 1 at the tail end that has been used can also be moved to the front end of the traction during the traction movement, so that a small number of traction auxiliary bases 1 can be used to complete the traction movement operation process over a longer distance, which is convenient for saving traction costs and is economical and practical.

[0036] The traction base unit is provided with two groups of moving seats 2, each group of the moving seats 2 is provided with two, and the two groups of the moving seats 2 are placed in the corresponding traction rails 11;

[0037] The mobile seat 2 includes a seat cavity 21, a roller group 22, a reinforcement block 23, a steering wheel 24 and a traction plate 25. The seat cavity 21 is a hollow cavity. An anti-skid pad 210 is fixed on the top surface of the seat cavity 21. The diesel generator set is placed on the seat cavity 21 through the anti-skid pad 210.

[0038] A roller group 22 is arranged at the bottom of the seat cavity 21, and the roller group 22 is composed of a plurality of solid rollers. Reinforcement blocks 23 are respectively fixed at both ends of the seat cavity 21, and a steering wheel 24 is arranged at the bottom of the reinforcement block 23. Specifically, the width of the seat cavity 21 is smaller than the width of the traction track 11, and two steering wheels 24 are arranged at the bottom of the reinforcement block 23. The outer side of the steering wheel 24 contacts the vertical side of the traction track 11, so that the traction direction can be fine-tuned during the traction process through the steering wheel 24, so as to accurately control the traction direction.

[0039] The steering wheel 24 is an electrically driven wheel, and the driving motor of each steering wheel 24 is independently controlled. By independently controlling the rotation speed of each steering wheel 24, a rotation speed difference can be formed on both sides of the seat cavity 21, so that the traction direction can be fine-tuned, which is convenient for accurate control of the traction operation.

[0040] A traction plate 25 is vertically fixed to the vertical side of the reinforcement block 23 at the front end of the seat cavity 21. Two adjustment plates 251 are sleeved on the outer side of the traction plate 25. The front ends of the traction plate 25 and the adjustment plate 251 are both provided with a connecting groove 253. A connecting protrusion 252 is fixed to the rear end of the adjustment plate 251. The connecting protrusion 252 is clamped in the connecting groove 253, and the connecting protrusion 252 is connected to the connecting groove through a connecting pin 254 that penetrates the connecting groove 253.

[0041] Specifically, the traction plate 25 and the adjustment plate 251 are rectangular plates of the same size. A plurality of threaded pin through holes 28 are arranged at equal intervals on the adjustment plate 251. A threaded pin 27 is threadedly connected to the reinforcement block 23 penetrated therethrough. The adjustment plate 251 is connected to the reinforcement block 23 through the threaded pin through holes 28 and the threaded pin 27, thereby completing the connection between the traction plate 25 and the adjustment plate 251 and between the two adjustment plates 251. Thus, the spacing between the two groups of movable seats 2 can be adjusted according to the bottom area of ​​the diesel generator set to be towed, which is convenient for adjusting the traction equipment according to diesel generator sets of different sizes, and is beneficial for broadening the scope of use of the traction equipment.

[0042] An intermediate groove 26 is also fixed in the seat cavity 21, and the intermediate groove 26 passes through the reinforcing block 23 at the rear end of the seat cavity 21. The connection between the moving seats 2 in the same group is completed through the action of the traction plate 25, the adjustment plate 251 and the intermediate groove 26. The adjustment plate 251 on the forward direction of the moving seat 2 is connected to the traction power, and the movement of the moving seat 2 in the same group is driven by the traction power.

[0043] The length of the middle groove 26 is at least twice the length of the adjustment plate 251, so that the adjustment plate 251 can be accommodated in the middle groove 26, which is convenient for flexibly adjusting the distance between two moving seats 2 in the same group, thereby improving the assembly flexibility between the moving seats 2 in the same group.

[0044] A plurality of vertical reinforcing plates 211 are fixed at equal intervals on the outside of the middle groove 26 in the seat cavity 21 , which improves the compressive strength of the seat cavity 21 , avoids deformation during use, and also increases the service life of the seat cavity 21 .

[0045] Two brake cylinders 29 are also installed in the seat cavity 21. The telescopic shaft of the brake cylinder 29 is sleeved on the side wall of the seat cavity 21, and a brake plate is fixed to the end of the telescopic shaft of the brake cylinder 29. During the traction process, the brake cylinder 29 can be used to brake the mobile seat 2, thereby preventing the mobile seat 2 from slipping when not being towed during use, thereby improving the stability and controllability of the traction process.

[0046] In summary, when using, first select a suitable number of traction auxiliary bases 1 according to the traction moving distance of the diesel generator set. When the number of traction auxiliary bases 1 is greater than 4 and the base of the diesel generator set is shorter than the length of two traction auxiliary bases 1, select 4 traction auxiliary bases. By moving the used traction auxiliary base 1 at the tail end to the front end of the traction, a small number of traction auxiliary bases 1 can be used to complete the traction moving operation process over a longer distance, thereby saving traction costs.

[0047] Then assemble the moving seat 2, select the spacing between the moving seats 2 in the same group according to the stress point of the diesel generator set, and then complete the assembly of the moving seats 2 in the same group by increasing or decreasing the number of adjustment plates 251. After the assembly is completed, move the stress point of the diesel generator set to the corresponding moving seat 2, connect the adjustment plate 251 with the traction power, and drive the movement of the moving seat 2 in the same group through the traction power, thereby completing the traction movement of the diesel generator set, which is convenient and practical.
