For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0032] like Figures 1 to 6 As shown, a suspended double-leaf door is mainly used in large shot blasting equipment, such as a large hook-type shot blasting machine. It is set at the entrance end of the shot blasting chamber and includes a left door 1 and a right door 2 that can be opened and closed relative to each other, as well as two corresponding support frames 3 and a drive mechanism. The two support frames 3 have the same structure and are both set in a triangular frame structure. They are fixedly installed at the top of the entrance end of the chamber. The bottom of the support frame 3 is fixedly installed with a horizontally arranged transverse guide rail 4 by multiple angle iron connectors 17 and matching bolts. The transverse guide rail 4 is made of I-beams, and limit plates 41 are fixedly installed at both ends. Multiple reinforcing beams are also erected on the support frame 3 to increase the stability and load-bearing strength of the support frame 3.

[0033] The aforementioned left door 1 and right door 2 are respectively suspended from the bottom horizontal guide rail 4 of the support frame 3 above their respective sides via a drive mechanism. They are aligned vertically and can both be moved along the horizontal guide rail 4 by the drive mechanism to achieve relative closing and opening. The drive mechanism includes multiple electric hoist trolleys 5, with at least two electric hoist trolleys 5 fixedly installed at the top of each door. Figure 12 As shown, the electric hoist trolley 5 includes a trolley frame 51, a running motor 52, a drive wheel 53, and a traveling wheel 54. The trolley frame 51 includes two opposing vertical plates. The drive wheel 53 and the traveling wheel 54 are rotatably mounted on the inner side of the corresponding vertical plates via shafts and bearings, and are coaxially arranged. The outer rim of the drive wheel 53 is also fixedly provided with an external tooth 55 that circumferentially surrounds it. The running motor 52 is bolted to the outer side of the vertical plate where the drive wheel 53 is located. On the side, the output shaft end is coaxially fixed with a drive gear, which meshes with the outer teeth 55 on the outer periphery of the drive wheel 53 through the running housing, and the drive wheel 53 can be driven to rotate by the running motor 52; the drive wheel 53 and the traveling wheel 54 are respectively mounted on both sides of the transverse guide rail 4 made of I-beam, and are mounted opposite each other to ensure that the entire trolley is engaged on the transverse guide rail 4 and can move along it; at the same time, the limiting plates 41 at both ends of the transverse guide rail 4 can prevent the electric hoist trolley 5 from detaching from the transverse guide rail 4 and avoid the door from falling off.

[0034] The bottom of the trolley bracket 51 of the electric hoist trolley 5 is bolted with a hanger 6, and the lower end of the hanger 6 is bolted to the top of the corresponding door body, allowing the electric hoist trolley 5 to suspend the door body and move it laterally. A ground rail 7, also made of I-beams, is fixedly installed on the ground below the left door body 1 and right door body 2, and is in the same vertical plane as the horizontal guide rail 4, with its center aligned. Correspondingly, at least two support guide wheels 8 are fixedly installed at the bottom of the left door body 1 and right door body 2, respectively. Figure 9 As shown, the wheel of the supporting guide wheel 8 is precisely engaged with the top surface of the ground rail 7 and can slide along it, working together with the electric hoist trolley 5 to support the weight of the door and ensure its stable operation. Meanwhile, a guardrail 9 is fixedly installed on the ground at the outermost end of the ground rail 7, outside the maximum opening and closing limit of the door, to remind workers to be careful and prevent accidental injury during door opening and closing, thus reducing safety hazards.

[0035] To ensure the sealing of the left door 1 and right door 2, door sealing devices are provided on opposite sides of the left door 1 and right door 2, in conjunction with... Figure 7 and Figure 10As shown, the door sealing device includes a matching sealing channel steel 11 and a sealing square tube 12. The sealing channel steel 11 is welded and fixed to the right side wall of the left door body 1, and is arranged along its height direction. A groove is provided on the side facing the right door body 2. The sealing square tube 12 is welded and fixed to the left side wall of the right door body 2, also arranged along its height direction. Its thickness is the same as the groove depth of the sealing channel steel 11. Two sealing strips 13 are fixedly installed on the door side walls on both sides of the sealing square tube 12. When the two doors are closed, the sealing square tube 12 is placed exactly in the groove of the sealing channel steel 11, and the two outer ends of the sealing channel steel 11 are aligned with the sealing strips 13, completing a relative seal. Figure 7 and Figure 11 As shown, the left door 1 and right door 2 are respectively equipped with side sealing devices at their ends away from their mating sides. Each side sealing device includes a sealing angle steel 14 arranged along the height direction of the door, with an L-shaped cross-section. It is welded and fixed to the corresponding side door and located on the side of the door facing the chamber, forming a U-shaped sealing groove 15 between itself and the door. Correspondingly, a buttress angle steel, also with an L-shaped cross-section, is fixedly installed on the outer wall of the chamber, arranged along the height direction of the chamber. When the two doors are closed, the movable end of the buttress angle steel fixed to the chamber is inserted into the U-shaped sealing groove 15 on the corresponding side, completing the relative sealing between the door and the chamber. Further optimized, a sealing strip 16 is fixedly installed on the movable end of the sealing angle steel 14, along its length. Similarly, a sealing strip is fixedly installed on the movable end of the buttress angle steel on the chamber.

[0036] Combination Figure 1 and Figure 8 As shown, anti-tipping devices 10 are also fixedly installed at the top of the left door 1 and the right door 2 respectively. The anti-tipping device 10 is made of square tube into a columnar structure and is vertically fixed to the top of the door by bolts. Each door has at least one such device. When the anti-tipping device 10 is fixed at the top of the door, its top part is placed between the horizontal guide rail 4 and the door body. The top of the anti-tipping device 10 is higher than the height of the horizontal guide rail 4. The length of the anti-tipping device 10 that is higher than the horizontal guide rail 4 is greater than the vertical distance between the bottom of the door and the ground, so as to prevent the door from falling and tilting outwards, effectively avoiding the occurrence of safety accidents.

[0037] The electric hoist trolleys 5 installed on the left door 1 and right door 2 can operate synchronously (electric hoist trolleys 5 located at the top of the same door operate synchronously, and electric hoist trolleys 5 located at the top of different door bodies also operate synchronously), so that the left door 1 and right door 2 move and open and close simultaneously; or they can operate asynchronously (electric hoist trolleys 5 located at the top of the same door operate synchronously, and electric hoist trolleys 5 located at the top of different door bodies operate asynchronously), so that a single door structure can be opened and closed.

[0038] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
