[0002] An air compressor is a device that converts the mechanical energy of a prime mover (usually an electric motor or a diesel engine) into gas pressure energy. When the air compressor is working, the temperature of the compressed gas will rise rapidly, resulting in an overly high temperature inside the air compressor. In addition, the air compressor in the power station is started and stopped frequently. Whether the air compressor can operate stably will greatly affect the safe operation of the pumped storage unit. Therefore, the air compressor needs to be regularly inspected and maintained. Now, the air compressor is usually hoisted and inspected by a gantry.

[0003] The gantry is a new type of small lifting gantry developed according to the daily production needs of small and medium-sized factories (companies) to carry equipment, warehouse goods in and out, lift and repair heavy equipment and transport materials. It is suitable for manufacturing molds, auto repair factories, mines, civil construction sites and other places where lifting is required. It is commonly used in construction to transport materials and move construction personnel up and down to achieve mechanization of lifting. It can reduce manpower, reduce production and operation costs, and improve work efficiency. The existing gantry is generally composed of a horizontal main beam and brackets on both sides of the horizontal main beam. When repairing some heavier machinery, the gantry is prone to shaking, and the air compressor is equipped with multiple sets of cylinders, which need to be disassembled and assembled in multiple directions. The existing gantry is a single set of beams, which is inconvenient for the maintenance of the hoisted equipment. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0022] The following gives specific embodiments.

[0023] As Figures 1 to 4 shown, a gantry for air compressor maintenance described in an embodiment of the present invention includes a main support beam 1. Main support frames 2 are provided on both sides of the main support beam 1, and a sub - support beam 3 perpendicular to and horizontally arranged with respect to the main support beam 1 is provided in the middle of the main support beam 1. One end of the sub - support beam 3 is fixed to the upper side of the main support beam 1, and a sub - support frame 4 for supporting the sub - support beam 3 is provided at the other end of the sub - support beam 3. A driving seat 5 that can move along the length directions of the main support beam 1 and the sub - support beam 3 is provided on the main support beam 1 and the sub - support beam 3.

[0024] The main support frame 2 includes a mounting block 6 for mounting the main support beam 1. A vertical support rod 29 is provided below the mounting block 6. Diagonal rods 7 that are inclined and symmetrically arranged with respect to the vertical plane are provided on both sides of the vertical support rod 29. A base 8 is provided below the diagonal rods 7, and casters 9 are provided below the base 8. A support mechanism is provided outside the casters 9.

[0025] The supporting mechanism comprises a frame-shaped shell 10 arranged on the lower side of the base 8, and two groups of inner walls of the frame-shaped shell 10 are provided with multiple groups of symmetrical and vertically arranged guide grooves 11, a horizontally arranged support plate 12 is provided in the guide groove 11, and sliders 13 corresponding to the guide grooves 11 are provided on both sides of the support plate 12, a hydraulic push rod 28 for driving the support plate 12 to move up and down is provided on the upper side of the support plate 12, and symmetrically arranged wedge blocks 14 are provided on both sides of the lower end of the support plate 12, and the other two groups of inner walls of the frame-shaped shell 10 are provided with symmetrical and obliquely arranged limit grooves 15, a support block 16 is provided between the limit grooves 15, and a limit rod 30 corresponding to the limit groove 15 is provided in the support block 16, a matching block 17 corresponding to the wedge block 14 is provided on the upper side of the support block 16, a friction block 18 for clamping the caster 9 is provided on the inner side of the support block 16, a clamping groove 19 is provided on the lower side of the wedge block 14, and a clamping block 20 corresponding to the clamping groove 19 is provided on the upper side of the matching block 17.

[0026] The support block 16 is an L-shaped support block, and a gasket 21 is disposed at the lower end of the support block 16 .

[0027] The auxiliary support frame 4 includes a U-shaped channel steel 22 for installing the auxiliary support beam 3, a triangular bracket 23 is provided on the lower side of the U-shaped channel steel 22, a cross bar 24 is provided on one side of the triangular bracket 23, a level 25 is provided on the cross bar 24, and casters 9 are provided at the bottom of the triangular bracket 23. Multiple groups of adjustment screws 26 for adjusting the bottom height of the triangular bracket 23 are provided on both sides of the casters 9.

[0028] A cushion block 27 is provided at the lower part of the adjusting screw 26 .

[0029] The principle of this application is that a secondary support beam is arranged on one side of the main support beam 1, and a secondary support frame 4 for supporting the secondary support beam is arranged at one end of the secondary support beam 3. The main support frame 2 and the secondary support frame 4 form a three-point support, and the support effect is better. In addition, the setting of the secondary support beam 3 can improve the disassembly and assembly direction angle of the air compressor, and the disassembly and assembly and maintenance are more convenient and reliable. The casters are self-locking casters, which are convenient for the transportation and movement of this application, but the contact area between the casters and the ground is small, and the friction with the ground is small. It can usually still move slightly in the locked state. A support mechanism is provided on one side of the casters of the main support frame 2 to play a better supporting role and prevent the movement of this application during the disassembly and assembly and maintenance of the air compressor due to the presence of the casters, which brings safety hazards. The supporting mechanism is arranged on the lower side of the base 8 and on the outer side of the caster 9. The support plate 12 is arranged on the front and rear sides of the caster 9. The support block 16 is arranged on the left and right sides of the caster 9, and a through groove corresponding to the caster mounting axis is provided in the support block 16. When in use, the support plate 12 is pushed downward by the hydraulic push rod 28. The hydraulic push rod 28 is connected to the support plate 12 through the hydraulic rod connector. During the downward movement of the support plate 12, the wedge block 14 will cooperate with the matching block 17 to press the support block 16 to move obliquely downward. Finally, the gasket 21 at the lower end of the support block 16 will be against the ground to increase friction, and the caster is clamped by the friction block 18 to further improve reliability.

[0030] The auxiliary support frame 4 includes a triangular bracket 23 in the shape of a right triangle. A U-shaped channel steel 22 for installing the auxiliary support beam 3 is provided on the upper side of the triangular bracket 23 to ensure that the auxiliary support beam is perpendicular to the auxiliary support frame 4, so that the cross bar 24 can reflect the horizontality of the auxiliary support beam 3, and the horizontality of the auxiliary support beam 3 is adjusted by adjusting the screw 26 and the supporting mechanism. The more the adjusting screw 26 is rotated downward, the higher the auxiliary support frame side will be, and the more the hydraulic push rod 28 is pushed downward, the higher the main support beam and the main support frame side will be. The auxiliary support beam is kept in a horizontal state by the hydraulic push rod and the adjusting screw, which prevents the auxiliary support beam from tilting and causing uneven force, thereby reducing the possibility of damage to the auxiliary support beam and the auxiliary support frame.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
