DETAILED DESCRIPTION

[0029] 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.

[0030] like Figure 1-3 As shown, the present invention provides a technical solution: a diesel generator set transport tool for a nuclear power plant, comprising a transport rack 1, on which two parallel transport rails 11 are arranged, and an extension plate 13 is fixed to the transport rack 1 near the base 2 in the plant, and the extension plate 13 is a rubber plate. The extension plate 13 can prevent the transport rack 1 from directly contacting the base 2 in the plant during use to cause damage to the transport rack 1, thereby improving the service life of the transport rack 1.

[0031] The outer end of the extension plate 13 abuts against the outer side of the in-plant base 2. The transfer track 11 on the transfer rack 1 has the same structure as the inner track 21 on the in-plant base 2. It is suitable for occasions where the inside and outside height difference is 500 to 900 mm. The height can be adjusted steplessly, which is beneficial for the transition of the diesel generator set from the in-plant base 2 to the transfer rack 1.

[0032] Three groups of transfer seats 3 are arranged in the transfer track 11. The transfer seats 3 are arranged in groups of two. The two transfer seats 3 in the same group are movably connected in the corresponding transfer track 11, and the two transfer seats 3 in the same group are connected by a fixing rod 4.

[0033] The transfer seat 3 includes a reinforced cavity 31, an anti-skid pad 32, a reinforcing plate 33, a load-bearing wheel 34 and a guide wheel 36. The top surface of the reinforced cavity 31 is fixed with an anti-skid pad 32, and the anti-skid pad 32 is in direct contact with the bottom of the diesel generator set to prevent the diesel generator set from relative slipping on the transfer seat 3.

[0034] A plurality of reinforcing plates 33 arranged parallel to each other are fixed in the reinforcing cavity 31 . The reinforcing plates 33 can improve the compressive strength of the reinforcing cavity 31 , thereby increasing the service life of the transfer seat 3 .

[0035] There are multiple load-bearing wheels 34, and the multiple load-bearing wheels 34 are installed at equal intervals on the bottom surface of the reinforced cavity 1.

The guide wheels 36 are remotely controlled electric drive wheels. The direction fine-tuning operation of the reinforced cavity 31 during movement can be completed through the guide wheels 36 on both sides.

[0037] A connecting shaft 39 is also fixed in the middle of the L-shaped plate 35. The connecting shafts 39 of two adjacent transfer seats 3 are connected by a connecting rod 5. The connecting rod 5 is two pin rods that cooperate with each other. The length of the connecting rod 5 can be adjusted by selecting the position of the pin, which is beneficial to the transportation and use of diesel generator sets of different sizes.

[0038] Two bidirectional cylinders 37 are also installed in the reinforced cavity 31 of the transfer seat 3. The two telescopic axes of the bidirectional cylinders 37 extend to the outside of the reinforced cavity 31, and brake blocks 38 are fixed to the outer ends of the telescopic axes of the bidirectional cylinders 37. The braking operation of the transfer seat 3 in the transfer track 11 can be completed through the action of the bidirectional cylinders 37 and the brake blocks 38.

[0039] The transfer frame 1 is fixed with reinforcing plates 12 on both sides parallel to the transfer track 11, and the bottom surface of the reinforcing plates 12 is staggeredly installed with hydraulic support mechanisms 6 and mechanical support mechanisms 7, and the support operation of the transfer frame 1 is completed with the cooperation of the hydraulic support mechanisms 6 and the mechanical support mechanisms 7.

[0040] Specifically, three connecting ear plates 14 are evenly spaced on the bottom surface of the reinforcing plate 12 , six hydraulic support mechanisms 6 are provided, each hydraulic support mechanism can bear 16 tons, and the six hydraulic support mechanisms 6 are correspondingly installed on the connecting ear plates 14 of the two reinforcing plates 12 .

[0041] The hydraulic support mechanism 6 includes an articulated seat 61, a hydraulic cylinder 62 and a first support seat 63. The articulated seat 61 is rotatably connected to the connecting ear plate 14. The bottom end of the hydraulic cylinder 62 is rotatably connected to the first support seat 63. The top end of the telescopic shaft of the hydraulic cylinder 62 is fixed to the bottom end of the articulated seat 61. The middle hydraulic support mechanism 6 acts as an intermediate support, and the hydraulic support mechanisms 6 on both sides are used for leveling, and can cooperate with each other to complete tilt leveling of less than 0.5°.

[0042] The articulated seat 61 is an articulated seat with a threaded locking pin, and the articulated seat 61 can be locked under the action of the threaded locking pin, so as to facilitate locking of the hydraulic support mechanism 6 after the adjustment is completed.

[0043] The reinforcing plate 12 has four oblong plates 15 fixed alternately between the three connecting ear plates 14. A mechanical support mechanism 7 is fixed to the bottom surface of each oblong plate 15. Each mechanical support mechanism 7 can bear 20 tons.

[0044] The mechanical support mechanism 7 includes a main support cylinder 71, a support rod 72, a U-shaped seat 74 and a lateral support cylinder 75. The support rod 72 is sleeved in the main support cylinder 71, and a second support seat 73 is rotatably connected to the bottom end of the main support cylinder 71.

The lateral support cylinder 75 is a two-stage telescopic cylinder, and the lateral support cylinder 75 is rotatably connected to the lateral support cylinder 75. The bottom end of 5 is rotatably connected with a third support seat 76. After the support of the hydraulic support mechanism 6 is completed, the mechanical support mechanism 7 is used for auxiliary support. The main support cylinder 71 and the support rod 72 cooperate with each other to adjust the overall height of the mechanical support mechanism 7, and then the length and inclination angle of the lateral support cylinder 75 are adjusted to assist the main support cylinder 71. A triangular stabilizing mechanism is formed between the lateral support cylinder 75 and the main support cylinder 71, so that the stable support operation of the mechanical support mechanism 7 can be completed through the main support cylinder 71 and the lateral support cylinder 75.
