DETAILED DESCRIPTION
[0030] In order to make the personnel in the technical field better understand the utility model scheme, the technical scheme in the embodiment of the utility model will be described clearly and completely in the embodiment of the utility model below, obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor should belong to the scope of protection of the utility model.
[0031] It should be noted that the terms "include" and "have" and their any variants in the specification and claims of the utility model and the above-mentioned drawings are intended to cover the non-exclusive inclusion, for example, the process, method, device, product or equipment including a series of steps or units does not have to be limited to the clearly listed steps or units, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.
[0032] The following will be combined with the drawings Figures 1-5 The application will be further described in detail.
[0033] Reference Figures 1-4The illustrated embodiment of a simple and compact cargo lifting mechanism for explosion-proof occasions comprises: a frame component 1, a shelf component 2 and a transmission component 3, wherein the frame component 1 comprises a main frame 11; the shelf component 2 comprises a shelf 21, and the shelf 21 is arranged in the main frame 11; the transmission component 3 comprises a mounting frame 31, a motor 32, a reducer 33, a first sprocket, two second sprockets, a first chain 34, a third sprocket, a second chain 35 and a rotating shaft 36, wherein the mounting frame 31 is placed on the top of the main frame 11, the motor 32, the reducer 33 and the rotating shaft 36 are arranged in parallel on the mounting frame 31 in sequence, the first sprocket is arranged at the output end of the motor 32, the two second sprockets are respectively placed at both ends of the reducer 33, the third sprocket is sleeved on the rotating shaft 36, the first chain 34 is sleeved on the first sprocket and the second sprocket on the same side as the first sprocket, and the second chain 35 passes through the third sprocket and the second sprocket on the same side as the third sprocket; one end of the second chain 35 is connected to the shelf 21 for driving the shelf 21 to perform lifting and lowering movements.
[0034] Based on the above structure, the shelf 21 is slidably set inside the main frame 11, and the second chain 35 is driven to move by the motor 32 and the reducer 33, thereby driving the shelf 21 to perform lifting and transporting the goods; since the motor 32 and the reducer 33 are separated and combined in the form of a first chain 34 transmission, this installation method allows the motor 32 and the reducer 33 to be set in parallel, so that the motor 32 and the reducer 33 can be installed in the middle of the transmission frame during installation. Compared with the conventional motor 32 and the reducer 33 directly installed on one side of the transmission frame, the required installation space is greatly reduced, and the requirements for the length direction of the installation space are greatly reduced, which has the advantages of simple and compact structure and small size; and the motor 32 is an explosion-proof motor, and the selection of a smaller specification explosion-proof variable frequency motor further reduces the space required for installation, so that the lifting mechanism meets the explosion-proof requirements and reduces the volume of the freight elevator.
[0035] like Figures 1-3 As shown, a number of second guide wheels 22 are provided on both sides of the shelf 21, and two vertically arranged shelf rails 13 are provided in the frame component 1. The number of second guide wheels 22 are respectively clamped on the two shelf rails 13. In this way, the movement of the shelf 21 is restricted and guided by the number of second guide wheels 22 to ensure the smooth operation of the shelf 21; and the second chain 35 is connected to the shelf 21 through the second chain bolt 23 provided on the top of the shelf 21; and in order to improve the safety of the operation of the shelf 21, a fall arrester 24 is provided on the top of the shelf 21 to prevent falling; a baffle 25 is provided on one side of the shelf 21. When the freight elevator is working, the baffle 25 is fixed by a pin to prevent the goods from moving out of the shelf. After reaching the position, the pin is taken out, and the baffle 25 can also play the role of a transport plate by rotating through the hinge, which is convenient for the freight cart to enter and exit.
[0036] like Figure 1 andFigure 5 In order to facilitate the lifting of goods, the application further comprises a counterweight component 4 arranged inside the main frame 11, the counterweight component 4 is connected with the suspended end (the end not connected with the goods shelf 21) of the second chain 35, and the counterweight component 4 offsets a part of the weight of the goods shelf 21 during the lifting of goods, so that the rated power of the motor 32 is reduced, and a smaller specification of the motor 32 can be selected, thereby further reducing the installation space and the overall volume.
[0037] As shown in Figure 5 The counterweight component 4 specifically comprises a counterweight frame 41, counterweight blocks 42, first chain bolts 43 and a plurality of first guide wheels 44, the counterweight blocks 42 are fixed in the counterweight frame 41 through counterweight fixing members, the first chain bolts 43 are arranged at the top of the counterweight frame 41, the second chain 35 is connected to the counterweight frame 41 through the first chain bolts 43, and the plurality of first guide wheels 44 are respectively arranged on both sides of the counterweight frame 41; two vertically arranged counterweight guide rails 12 are arranged in the frame component 1, the plurality of first guide wheels 44 are respectively clamped on the two counterweight guide rails 12, the movement of the counterweight frame 41 is limited and guided through the plurality of first guide wheels 44, the counterweight component 4 runs stably, and a buffer pad 45 is arranged at the bottom of the counterweight frame 41, so that the counterweight component 4 is buffered when falling to the bottom.
[0038] Further optimization is that the main frame 11 is formed by square tubes connected through bolts, various sensors are arranged to detect the position of the goods shelf 21 in real time, and the goods shelf 21 can be stopped at a fixed position when ascending and descending through PLC control.
[0039] Compared with the conventional lifting mechanism using an electric hoist or a motor reducer integrated as a power source, the parallel installation of the explosion-proof motor and the reducer in the design can meet the requirements of some indoor paint spraying control occasions for explosion protection.
[0040] The parallel installation of the explosion-proof motor and the reducer through the chain greatly reduces the volume of the installation frame. The design that the counterweight component is connected with the goods shelf through the second chain also greatly reduces the power required by the motor when the goods are lifted. When the motor is selected, the specification of the motor can be one to two grades smaller than that in the conventional design, thereby further reducing the volume of the motor and the width of the lifting mechanism.
[0041] The design is very suitable for large equipment indoor paint spraying control occasions and can effectively reduce the space requirement of the lifting mechanism.
[0042] The above is only a preferred embodiment of the application, and the utility model is not limited to the above examples. It can be understood that other improvements and changes directly derived or thought of by those skilled in the art without departing from the spirit and concept of the utility model should be considered to be included in the protection scope of the utility model.
