Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 5, the utility model relates to a roots fan service rack, including bottom plate 1, 1 bottom surface of bottom plate is connected with truckle 8, and truckle 8 is fixed in bottom surface four corners position of bottom plate 1, including preceding truckle and back truckle, preceding truckle is directional truckle, and the universal caster of back truckle for having the brake, when overhauing the operation, for avoiding this service rack to produce to remove, the brake of stepping on universal caster realizes fixedly. The upper portion of the bottom plate 1 is connected with the placing plate 5, the sliding grooves 51 are formed in the left side and the right side of the top surface of the placing plate 5, as shown in fig. 3 and 5, the length direction of the sliding grooves 51 is the front-back direction, the pressing plate 7 is arranged above the sliding grooves 51, the adjusting grooves 71 in the left-right direction are formed in the pressing plate 7, the number of the adjusting grooves 71 is two, the adjusting bolts 6 with upward threaded ends are arranged in the sliding grooves 51 and the adjusting grooves 71 in a penetrating mode, the large head ends of the adjusting bolts 6 are smaller than the width of the sliding grooves 51, and therefore the lower ends of the adjusting bolts 6 are blocked by the sliding grooves 51 and cannot be taken down from the upper portion. A fastening nut 61 in threaded connection with the adjusting bolt 6 is arranged above the pressing plate 7, so that the upper side of the pressing plate 7 is blocked by the fastening nut 61, the pressing plate 7 has the freedom of up-and-down movement, and meanwhile, the adjusting groove 71 on the pressing plate 7 is matched with the adjusting bolt 6 to enable the pressing plate 7 to have the freedom of left-and-right movement. During operation, place the roots fan that will wait to overhaul on placing board 5 through the overhead traveling crane, the maintenance platform that will load the roots fan again pushes away maintenance department, and this maintenance platform stops steady back lifts and moves clamp plate 7 to the inboard simultaneously for clamp plate 7 presses on the base top surface of fan, screws up fastening nut 61 on the adjusting bolt 6, makes clamp plate 7 compress tightly the fan base, and then realizes fixing the roots fan, avoids the fan to produce to remove and influence the maintenance at the operation in-process.

The bottom plate 1 top surface both sides fixedly connected with curb plate 11, swivelling joint has left dextrorotation screw rod 2 on the curb plate 11, and the left half section of controlling the screw rod 2 is the levogyration threaded rod, and the right half section is the dextrorotation threaded rod. The side plate 11 is further connected with a sliding guide rod 23 with an axis parallel to the left and right screw rods 2, and the sliding guide rod 23 is fixed on two sides of the left and right screw rods 2 in the embodiment to play a role in sliding guidance. One end of the left-handed screw 2 is fixedly connected with a handle 24, which is convenient for applying force to rotate the left-handed screw 2. The left-handed screw 2 is connected with a left thread block 21 and a right thread block 22 in a symmetrical thread fit manner, as shown in fig. 1 and 4, the thread turning directions of the left thread block 21 and the right thread block 22 are opposite, a left-handed thread hole is formed in the left thread block 21 and is connected with a left half section of the left-handed screw 2 in a thread fit manner, and a right-handed thread hole is formed in the right thread block 22 and is connected with a right half section of the left-handed screw 2 in a thread fit manner. Both the left screw block 21 and the right screw block 22 are slidably connected to the sliding guide rod 23, and when the handle 24 is rotated, the left-right screw rod 2 is rotated to drive the left screw block 21 and the right screw block 22 to move towards or away from each other at the same time. Roof 4 is equipped with above left side screw thread piece 21 and the right screw thread piece 22, roof 4 is connected and is being placed board 5 below, all articulated hinge rod 3 that has between left side screw thread piece 21 and right screw thread piece 22 and the roof 4, hinge rod 3 upper end and roof 4 bottom are articulated, the lower extreme is articulated with left screw thread piece 21 or right screw thread piece 22, as shown in figure 1, two hinge rod 3 mutual symmetry just remain the splayed all the time, only along with left screw thread piece 21 and right screw thread piece 22 the motion of moving towards each other or back to each other, the contained angle between two hinge rod 3 changes, utilize this kind of contained angle change to push up or get off roof 4, make the height of placing board 5 change. In fig. 1, when rotatory left and right handed screw rod 2 makes left thread piece 21 and right thread piece 22 move in opposite directions, the contained angle grow between two hinge bar 3 about, place board 5 can the downstream, in the same way, when rotatory left and right handed screw rod 2 makes left thread piece 21 and right thread piece 22 move back to back, the obtuse angle contained angle between two hinge bar 3 about diminishes, place board 5 and can the up-motion, make through above-mentioned structure and place board 5 can the up-and-down motion, and then what adapt to the user of different heights conveniently carries out the fan and overhauls, the mode of heightening of this kind of mechanical type compares in shearing formula lifting machine electric control more reliably.

Seted up the perpendicular slide opening of a plurality of on roof 4, place 5 bottom surfaces of board and be connected with sliding fit and connect in the perpendicular slide bar 53 of perpendicular slide opening, the cover is equipped with bradyseism spring 54 on the perpendicular slide bar 53, as shown in fig. 1, 5, the vibrations that the fan started the back production can inhale shake through bradyseism spring 54 for this maintenance platform is more stable, and life is longer.

A plurality of sliding grooves 51 are formed in the left-right direction of the placing plate 5, and as shown in fig. 3 and 4, the adjusting bolts 6 and the pressing plate 7 are installed in different sliding grooves 51, so that the fans with a large width can be overhauled and fixed.

The top surface of the placing plate 5 is connected with the anti-slip layer 52, and the fan is not easy to move left and right due to large friction force after being started; the bottom surface of the pressing plate is connected with an anti-slip rubber layer, the friction force between the pressing plate 7 and the top surface of the fan base is larger, and the pressing and fixing effects of the pressing plate 7 are better.

The working process is as follows: the Roots blower to be overhauled is placed on the placing plate 5 through the crown block, and then the overhaul platform carrying the Roots blower is pushed to an overhaul position; after the maintenance platform is stopped and stable, the pressure plate 7 is lifted upwards and moved inwards at the same time, so that the pressure plate 7 is pressed on the top surface of the base of the blower, and the fastening nut 61 on the adjusting bolt 6 is screwed down, so that the pressure plate 7 is pressed tightly on the base of the blower, and further the fixation of the Roots blower is realized; when needs are adjusted and are placed board 5 and place the fan height on the board 5, rotate handle 24, rotate through left dextrorotation screw rod 2 and drive left screw block 21 and right screw block 22 simultaneously in opposite directions or back-to-back motion, the motion of left screw block 21 and right screw block 22 makes the contained angle between two hinge bar 3 change, and then drives roof 5 and places board 6 and rise or descend.
