Description

Technical Field

[0001] The invention relates to the technical field of compressors, and in particular to a gas compressor with a supporting mechanism. Background Art

[0002] A gas compressor is a power device that converts mechanical energy into gas pressure energy. It is often used to provide gas power for pneumatic tools and is widely used in many industries. In the process of oil and natural gas drilling, gas compressors are used to provide the necessary pressure to drive drill pipes, extract groundwater and perform other related operations. Gas compressors generally require a movable support mechanism for their installation.

[0003] As disclosed in the authorization announcement number CN116518208B, a gas compressor with a support mechanism includes a gas compressor body and a stabilizing plate for stably placing the gas compressor body and having a U-shaped structure, and a mounting seat is fixedly connected to the bottom surface of the stabilizing plate. When the driving shaft of the present invention rotates, with the cooperation of the gears, the rotation direction of the driven shaft is opposite to that of the driving shaft. At this time, the two linkage rods in different directions move along the rotation direction of the driving shaft and the driven shaft, and the end of the linkage rod pushes the transmission rod downward, and the shaft block approaches from one end of the movable groove to the other end until one end of the movable groove abuts against the outer surface of the shaft block. At this time, the transmission rod pushes the support plate downward, and the stability of the stabilizing plate is supported by the support plate, providing stable support for the gas compressor body, and the entire support structure can be automatically lifted.

[0004] Although the above-mentioned supporting mechanism can provide support when the gas compressor is working, during use, drilling and mining are generally located outdoors, and the gas compressor is only supported on the ground by the supporting mechanism. During use, the compressor will vibrate as the motor operates, constantly squeezing the loose soil at the bottom. The gas compressor may tip over due to uneven supporting force.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 7 As shown, a gas compressor with a supporting mechanism includes a supporting plate 1 and a compressor body 3. A mounting frame 2 is provided on the upper surface of the supporting plate 1. The compressor body 3 is mounted on the supporting plate 1 through the mounting frame 2. The supporting mechanism also includes a base 4 and a lifting plate 42. The base 4 is fixedly arranged on the lower surface of the supporting plate 1. A square ring groove 41 is provided at the bottom of the base 4. A lifting structure is provided inside the square ring groove 41. The lifting plate 42 is arranged inside the square ring groove 41 through the movable cooperation of the lifting structure. A plurality of universal wheels 43 are distributed at the bottom of the lifting plate 42. A plurality of storage grooves 40 are provided on the outer side surface of the base 4. The storage grooves 40 are all rotatably connected with a rotating plate 56. The bottom of the rotating plate 56 is rotatably connected to the supporting plate 1 through a rotating shaft. The rotating plate 56 can rotate along the rotating shaft. The rotating plate 56 rotated to a vertical direction is engaged in the storage groove 40. 6 After rotating ninety degrees, its horizontal surface is flush with the bottom of the base 4. A linkage structure is provided between each rotating plate 56 and the lifting plate 42. The lifting plate 42 rises to drive the rotating plate 56 to rotate. A cavity 6 is provided inside the rotating plate 56. A rivet 65 is also movably provided inside the cavity 6. The rivet 65 is used for anchoring. When it needs to be fixed, the hydraulic cylinder 44 is shortened to drive the lifting plate 42 to move upward, so that the universal wheel 43 can be fully stored in the square ring groove 41. In the process of the lifting plate 42 moving upward, the linkage structure pushes the rotating plate 56 to rotate outward. When the universal wheel 43 shrinks into the square ring groove 41, the hinged rod 55 pushes the rotating plate 56 to rotate ninety degrees, so that the rotating plate 56 is flush with the bottom of the base 4, thereby increasing the contact area between the support mechanism and the ground, reducing the local pressure at the bottom of the support mechanism, and reducing the risk of the support mechanism tipping over.

[0030] In some specific embodiments, such as Figure 4As shown, in order to facilitate the storage of the universal wheel 43 into the square ring groove 41, the lifting structure includes a plurality of hydraulic cylinders 44, and the plurality of hydraulic cylinders 44 are distributed and fixed in the square ring groove 41. The driving ends of the hydraulic cylinders 44 are fixedly connected to the lifting plate 42. When the hydraulic cylinders 44 are started to retract, the lifting plate 42 and the universal wheel 43 can be driven to rise and fall synchronously.

[0031] In some specific embodiments, such as Figure 4 As shown, in order to facilitate the rotation of the rotating plate 56 while the lifting plate 42 moves, each linkage structure includes a limiting groove 54, a gear 51, a movable rack 52 and a hinge rod 55. The limiting groove 54 is fixedly arranged on the top of the lifting plate 42, and a support frame is fixedly arranged inside the square ring groove 41. The gear 51 is rotatably connected to the inside of the square ring groove 41 through the support frame. A limiting structure is also arranged inside the square ring groove 41. The movable rack 52 is arranged inside the square ring groove 41 for upward and downward movement through the limiting structure. One side of the gear 51 is meshed with the fixed rack 5, and the other side is meshed with the movable rack 52. A clearance groove (not marked in the figure) for the movable rack 52 to pass through is opened on the lifting plate 42, so that the movable rack 52 can pass through the clearance groove when moving downward. The side of the bar 52 away from the gear 51 is rotationally connected to the end of the hinge rod 55, and the other end of the hinge rod 55 is rotationally connected to the side wall of the rotating plate 56. The limiting structure includes a limiting groove 54. The limiting groove 54 is vertically penetrated inside the movable rack 52. A square rod 53 is fixedly arranged on the top plate of the storage slot 40. The square rod 53 is slidably connected inside the limiting groove 54. The setting of the square rod 53 has a limiting effect on the movement of the movable rack 52. In the process of the lifting plate 42 moving upward, the top fixed rack 5 is driven to move upward, thereby driving the gear 51 meshing with the fixed rack 5 to rotate. When the gear 51 rotates, under the limiting action of the square rod 53, the movement direction of the movable rack 52 is opposite. At this time, in the process of the movable rack 52 moving downward, the rotating plate 56 is pushed to rotate outward.

[0032] In some specific embodiments, such as Figure 1 As shown, in order to reduce the floor space occupied by the equipment, the size of the storage groove 40 is larger than that of the rotating plate 56, so that the rotating plate 56 can be completely stored in the storage groove 40, and fixing seats 7 for fixation are provided on both sides of the rotating plate 56. When the equipment is located on a concrete floor, the rotating plate 56 fits the ground, and the entire equipment can be fixed by passing bolts through the fixing seat 7. The fixing seat 7 is engaged in the storage groove 40 for easy storage.

[0033] In some specific embodiments, such as Figure 5 or Figure 7As shown, in order to reduce the movement of the entire device, a storage structure is provided inside the cavity 6, and the storage structure includes a screw 62 and a driving plate 61. The screw 62 is rotatably connected inside the cavity 6. A small motor 63 that drives the screw 62 to rotate is provided on the rotating plate 56. The driving plate 61 is located inside the cavity 6 and is threadedly connected to the screw 62. A guide rod with a limiting function is provided in the cavity, and the guide rod passes through the driving plate 61 and is slidably connected thereto. A plurality of rivets 65 are also provided on the driving plate 61. A plurality of through holes 64 are provided on the side of the rotating plate 56 away from the base 4. The rivets 65 are aligned with the corresponding through holes 64. The width of the cavity 6 is greater than the length of the rivets 65, so that all the rivets 65 can be retracted into the cavity 6. The small motor 63 is started to drive the screw 62 to rotate, and the driving plate 61 meshing with the screw 62 moves. During the movement of the driving plate 61, the rivet 65 is driven to extend out of the through hole 64 and be plugged into the ground, so as to avoid the vibration of the compressor body 3 during operation, causing the entire supporting mechanism to drive the compressor body 3 to move.

[0034] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0035] During the movement, the hydraulic cylinder 44 is extended to drive the lifting plate 42 to move downward, so that the universal wheel 43 can extend out of the square ring groove 41, so that the surface of the universal wheel 43 is in contact with the ground, and the supporting structure with the compressor body 3 can be pushed to move as a whole. When the supporting plate 1 carrying the compressor body 3 reaches the destination, the hydraulic cylinder 44 is shortened to drive the lifting plate 42 to move upward, so that the universal wheel 43 can be completely stored in the square ring groove 41, and in the process of the lifting plate 42 moving upward, the fixed gear on the top is driven The rack 5 moves upward, thereby driving the gear 51 meshing with the fixed rack 5 to rotate. When the gear 51 rotates, the moving rack 52 moves in the opposite direction under the limiting action of the square rod 53. At this time, during the downward movement of the moving rack 52, the hinged rod 55 pushes the rotating plate 56 to rotate outward. When the universal wheel 43 shrinks into the square ring groove 41, the hinged rod 55 pushes the rotating plate 56 to rotate ninety degrees, so that the rotating plate 56 is flush with the bottom of the base 4, thereby increasing the contact area between the support mechanism and the ground and reducing The local pressure at the bottom of the support mechanism reduces the risk of the support mechanism tipping over. At this time, the small motor 63 is started to drive the screw 62 to rotate, and the drive plate 61 meshed with the screw 62 moves. During the movement of the drive plate 61, the rivet 65 is driven to extend out of the through hole 64 and inserted into the ground to avoid the vibration of the compressor body 3 during work, causing the entire support mechanism to drive the compressor body 3 to move. When the compressor body 3 finishes working, the hydraulic cylinder 44 pushes the lifting plate 42 downward, so that the hydraulic cylinder 44 contacts the ground for easy movement. During the rising process of the lifting plate 42, the rotating plate 56 is driven to rotate inward, so that the rotating plate 56 is stored in the storage groove 40, reducing the floor space occupied during the movement. At the same time, the screw 62 rotates to drive the drive plate 61 to move, so that the drive plate 61 drives the rivet 65 to be stored in the cavity 6, avoiding the protruding rivet 65 from scratching the staff. By storing the rotating plate 56 in the storage groove 40 and the rivet 65 in the cavity 6, the entire support mechanism has a compact structure and a small floor space.

[0036] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
