Description

Technical Field

[0001] The utility model belongs to the technical field of air compressor maintenance and lifting, in particular to a gantry used for air compressor maintenance. Background Art

[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 starts and stops 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 crane is a new type of small-scale lifting gantry developed to meet the daily production needs of small and medium-sized factories (companies), such as the handling of equipment, the loading and unloading of goods in warehouses, the lifting and maintenance of heavy equipment, and the transportation of materials. It is suitable for mold manufacturing, auto repair factories, mines, civil construction sites, and other places where lifting is required. It is commonly used in construction to transport materials and to move construction personnel up and down, thus realizing the mechanization of lifting. It can reduce manpower, lower production and operating costs, and improve work efficiency. Existing gantries generally consist of a horizontal main beam and brackets on both sides of the horizontal main beam. When repairing some heavier machinery, the gantry crane is prone to shaking. In addition, the air compressor is equipped with multiple sets of cylinders, which need to be disassembled and assembled in multiple directions. The existing gantry crane is usually a single set of beams, which makes it inconvenient to repair the hoisted equipment. Utility Model Content

Based on the embodiments in the present utility model, 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 utility model.

[0022] The following gives specific embodiments.

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

[0024] The main support frame 2 includes an installation block 6 for installing the main support beam 1. A vertical support rod 29 is provided below the installation block 6. Inclined 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 inclined rods 7, and casters 9 are provided below the base 8. A support mechanism is provided outside the casters 9.

[0025] The support mechanism includes a frame-shaped shell 10 arranged on the lower side of the base 8, and two groups of inner walls of the frame shell 10 are provided with multiple groups of symmetrical and vertically arranged guide grooves 11, and a horizontally arranged support plate 12 is provided in the guide groove 11. Slide blocks 13 corresponding to the guide grooves 11 are provided on both sides of the support plate 12, and 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. Symmetrical 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 shell 10 are provided with symmetrical and oblique limit grooves 15, and 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, and a friction block 18 for clamping the caster 9 is provided on the inner side of the support block 16. A card slot 19 is provided on the lower side of the wedge block 14, and a card block 20 corresponding to the card slot 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 provided at the lower end of the support block 16 .

[0027] The secondary support frame 4 includes a U-shaped channel steel 22 for installing the secondary 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 spirit level 25 is provided on the cross bar 24. 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 portion of the adjusting screw 26 .

[0029] The principle of this application is that a secondary support beam is set on one side of the main support beam 1, and a secondary support frame 4 for supporting the secondary support beam is set 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, which has a better support effect. In addition, the setting of the secondary support beam 3 can improve the disassembly and assembly direction angle of the air compressor, making disassembly and assembly more convenient and reliable. The casters are self-locking casters, which are convenient for the transportation and movement of this application. However, the contact area between the casters and the ground is small, and the friction with the ground is small. In the locked state, it can usually still move slightly. 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 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 outside of the caster 9. The support plate 12 is arranged on the front and rear sides of the caster 9, and the support block 16 is arranged on the left and right sides of the caster 9. 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 contact 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 is provided on the upper side of the triangular bracket 23 for installing the auxiliary support beam 3 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. The horizontality of the auxiliary support beam 3 is adjusted by adjusting the screw 26 and the support mechanism. The more the adjusting screw 26 is rotated downward, the higher the auxiliary support frame side will be. 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 hydraulic push rod and the adjusting screw are used to make the auxiliary support beam in a horizontal state, avoiding 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.
