Both ends of the left and right beams are provided with side connecting plates, and the two side connecting plates are fixedly connected to the middle longitudinal beam of the fixing frame through the fixing assembly.

[0007] Preferably, the fixing assembly includes two support plates, with an intermediate connecting plate between the upper ends of the support plates, and the intermediate connecting plate is fixedly connected to the two side connecting plates by a number of bolt pairs.

[0008] Preferably, the support plate is sleeved on the intermediate longitudinal beam, and a pin is provided between the lower ends of the support plate.

[0009] Preferably, both the left and right beams are provided with two symmetrically arranged hanging plates, and a pin is provided between the two hanging plates on the same beam.

[0010] Preferably, the left end of the left beam and the right end of the right beam both extend beyond the range of the fixed frame.

[0011] Preferably, each of the crossbeams is provided with a mounting base at its lower end, and the mounting base is provided with mounting holes.

[0012] The beneficial effects of this utility model are as follows: By fixing the upper end of the column to the fixed frame through connecting components, and fixing the crossbeam to the fixed frame through several connecting components, the utility model enables the column, fixed frame and crossbeam to be disassembled and assembled. Compared with the prior art, it is convenient to disassemble and assemble, and convenient to transport and install on site.

[0013] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0018] See Figure 1 , Figure 2 This utility model discloses a maintenance frame for a chain bucket elevator, comprising two crossbeams 1, a fixed frame 2, several columns 3, and several connecting components 4. The upper ends of the columns 3 are all fixedly connected to the fixed frame 2 through the connecting components 4. The crossbeams 1 are all fixedly mounted on the fixed frame 2 through the several connecting components 4. The connecting components 4 include an upper connecting plate 41 and a lower connecting plate 42, which are fixedly connected together by bolt pairs 7.

[0019] The crossbeam 1 includes a left beam 11, a right beam 12 and a fixing component 13. The left beam 11 and the right beam 12 are provided with side connecting plates 14 at their opposite ends. The two side connecting plates 14 are fixedly connected to the middle longitudinal beam 21 of the fixing frame 2 through the fixing component 13.

[0020] The fixing component 13 includes two support plates 131, and an intermediate connecting plate 132 is provided between the upper ends of the support plates 131. The intermediate connecting plate 132 is fixedly connected to the two side connecting plates 14 by a number of bolt pairs 7.

[0021] The support plate 131 is sleeved on the intermediate longitudinal beam 21, and a pin 16 is provided between the lower ends of the support plate 131.

[0022] The left beam 11 and the right beam 12 are each provided with two symmetrically arranged hanging plates 15, and a pin 16 is provided between the two hanging plates 15 on the same beam.

[0023] The left end of the left beam 11 and the right end of the right beam 12 both extend beyond the range of the fixed frame 2.

[0024] Each of the crossbeams 1 is provided with a mounting base 6 at its lower end, and the mounting base 6 is provided with mounting holes 5.

[0025] The working process of this utility model:

[0026] In the operation of this utility model, a maintenance frame for a chain bucket elevator can be separated by disassembling all the bolt pairs 7 to separate the column 3, the fixing frame 2, and the crossbeam 1. During assembly, the corresponding upper connecting plate 41 and lower connecting plate 42 are fixedly connected by several bolt pairs 7, and the corresponding side connecting plate 14 and middle connecting plate 132 are fixedly connected by several bolt pairs 7.

[0027] The pin 16 on the hanging plate 15 is used to hang the manual hoist. It is located directly above the corresponding chain, so the chain can be lifted directly for maintenance or replacement.

[0028] The pin 16 on the hanging plate 15 is used to hang a manual hoist, and can also be used to lift the entire transmission device for maintenance and replacement.

[0029] The pin 16 on the support plate 131 is used to hang a manual hoist for hoisting the hopper, for maintenance or replacement.

[0030] The portions of the left beam 11 and right beam 12 that extend beyond the fixed frame 2 are used for hoisting the drive unit and for the maintenance and replacement of the drive unit.
