Description

Technical Field

[0001] This utility model mainly relates to the field of gas filling technology, specifically an auxiliary tooling for gas filling. Background Technology

[0002] In the field of gas filling technology, gas cylinders, as the core carriers for gas storage and transportation, are of paramount importance in terms of the safety and efficiency of their transfer and filling processes.

[0003] Currently, the gas filling auxiliary tooling commonly used in the industry has limitations when dealing with gas cylinders of different specifications: On the one hand, the clamping structure of traditional tooling is mostly designed with fixed dimensions, which can only be adapted to gas cylinders of a single height or diameter. When dealing with gas cylinders of different specifications (such as industrial oxygen cylinders, acetylene cylinders, etc., with a height difference of more than 30cm and a diameter difference of more than 10cm), special tooling needs to be changed, which not only increases the cost of equipment investment, but also leads to low filling efficiency due to the change of process; On the other hand, the push parts of existing tooling are at a fixed height, which cannot adapt to the force application needs of operators of different heights, and long-term operation can easily lead to occupational health problems such as lumbar strain. Utility Model Content

[0004] This utility model provides a significantly different solution to the problem of overly simplistic existing technical solutions. It primarily offers an auxiliary tooling for gas filling, addressing the limitations of commonly used gas filling auxiliary tooling in the background section when adapting to different gas cylinder specifications: First, the clamping structure is of a fixed size, only suitable for cylinders of a single height or diameter. When handling cylinders with significant size differences (e.g., a height difference exceeding 30cm or a diameter difference exceeding 10cm between industrial oxygen and acetylene cylinders), a dedicated tooling is required, increasing equipment costs and reducing operational efficiency. Second, the fixed height of the pushing component cannot accommodate the force requirements of operators of different heights, easily leading to occupational health problems such as lumbar strain.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: An auxiliary tooling for gas filling includes a moving component, a guide rod on the moving component, and a limit component slidably disposed on the guide rod.

[0006] The moving component includes a housing, an electric push rod is installed through the top of the inner wall of the housing, a fixed plate is installed at the top telescopic end of the electric push rod, an arc-shaped plate is installed on one side of the fixed plate via a mounting bracket, and a base plate is provided at the bottom of the arc-shaped plate. This mechanism is used to move gas cylinders.

[0007] The limiting assembly includes a clamping plate and a movable block slidably mounted on the outer wall of the guide rod. A threaded rod is threaded through the middle of one side of the movable block. The threaded rod is rotatably connected to the clamping plate. The clamping plate is used to clamp the gas cylinder in conjunction with the arc-shaped plate.

[0008] More preferably, a connecting block is installed on the top of the guide rod, and a support block is slidably installed on the outer wall of the guide rod. There are two guide rods in total, and the two guide rods are symmetrically distributed about the vertical central axis of the support block. The guide rods have a number of evenly spaced circular holes along their length. The support block has connecting holes corresponding to the circular holes on the guide rods. The support block and the guide rods are connected by bolts passing through the connecting holes and the corresponding circular holes.

[0009] More preferably, the outer wall of the box is symmetrically provided with two support legs, and the bottom of each support leg is equipped with a braked universal wheel at the end away from the box, and the bottom of the box is equipped with a braked universal wheel at the end away from the support leg.

[0010] More preferably, two fixed tubes are symmetrically installed on the top of the box, and a push handle is slidably installed on the inner wall of each fixed tube. The outer wall of the push handle is provided with a number of evenly spaced screw holes along its axial direction. A connection hole is provided on the outer wall of each fixed tube near the top. The push handle is connected to the fixed tube by a hand-tightening bolt, and the hand-tightening bolt passes through the connection hole of the fixed tube and the corresponding screw hole on the push handle.

[0011] More preferably, two first sliding rods are symmetrically installed at the bottom of the fixing plate, and a sliding hole corresponding to the first sliding rod is opened at the top of the box body. The first sliding rod passes through the sliding hole and forms a sliding fit with the box body.

[0012] More preferably, the top of the movable block is provided with an insertion block, the top of the connecting block is provided with an insertion hole that matches the insertion block, the top of the insertion block is provided with a slot, the slot is constructed as an interface for inserting an external insertion block to limit the displacement of the movable block; a handle is installed on one side of the movable block; two symmetrically distributed second slide rods are slidably installed through one side of the movable block, and the ends of the second slide rods are connected to the clamping plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This auxiliary tooling, through an arc-shaped plate, guide rod, support block, and limiting component, features a continuously adjustable multi-hole design along the guide rod (the spacing between the holes is set according to the standard gas cylinder height difference). Different height positions are fixed by bolts, limiting the downward stroke of the limiting component and adapting to gas cylinders of different heights. The concave arc surface of the M-shaped clamping plate, combined with symmetrically distributed second sliding rods, adapts to gas cylinders of different diameters. The fixed curved surface of the arc-shaped plate and the curved surface of the clamping plate form a limiting structure. Compared to traditional auxiliary tooling, this allows for the transfer of gas cylinders of different diameters and heights, improving the tooling's applicability. 2. This auxiliary tool, through the tube and the push lever, allows for multi-position height adjustment of the push lever inside the tube (locked by hand-tightening bolts) when using the auxiliary tool. It can adapt to the force application posture of operators of different heights and meet the force application needs of operators of different heights, thereby reducing the risk of lumbar strain.

On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0019] Please refer to the appendix carefully. Figure 1-3 An auxiliary tooling for gas filling includes a movable component 1, a guide rod 2 mounted on the movable component 1, and a limit component 5 slidably mounted on the guide rod 2.

[0020] The mobile component 1 includes a housing 101 (a battery is installed inside the housing 101, and an electric push rod 105 is connected to the battery via wires; a charging interface and a control switch are provided on the side wall of the housing 101). A guide rod 2 is installed on the top of the housing 101, and an electric push rod 105 is installed through the top of the inner wall of the housing 101 (a fixed seat is welded to the top of the inner wall of the housing 101, and the bottom flange of the electric push rod 105 is fixed to the fixed seat by bolts). A fixed plate 106 is installed at the top telescopic end of the electric push rod 105. Two symmetrically distributed arc-shaped plates 109 are installed on one side of the fixed plate 106 via a mounting bracket 108. A base plate 1010 is installed at the bottom of the arc-shaped plates 109. This mechanism is used to transport gas cylinders.

[0021] The limiting component 5 includes a clamping plate 505 and a movable block 501 that is slidably installed on the outer wall of the guide rod 2. A threaded rod 506 is threaded through the middle of one side of the movable block 501. The threaded rod 506 is rotatably connected to the clamping plate 505. The clamping plate 505 is M-shaped and is used to clamp the gas cylinder in conjunction with the arc plate 109.

[0022] In this embodiment, as Figure 1 As shown, a connecting block 3 is installed on the top of the guide rod 2, and a support block 4 is slidably fitted on its outer wall. The two guide rods 2 are symmetrically distributed about the vertical central axis of the support block 4, forming a double-sided guide structure. Several evenly spaced circular holes are opened along the length of the guide rod 2. The support block 4 has connecting holes corresponding to the circular holes on the guide rod 2. The support block 4 and the guide rod 2 are connected by bolts passing through the connecting holes and the corresponding circular holes. By selecting the circular holes at different heights on the guide rod 2 for bolting, the vertical installation position of the support block 4 can be adjusted. Since the support block 4 is located below the moving path of the limiting component 5, this adjustment can limit the lower limit of the sliding stroke of the limiting component 5, thereby adapting to gas cylinder specifications of different heights.

[0023] In this embodiment, as Figure 2As shown, the two ends of the housing 101 are provided with heat dissipation holes, and dustproof mesh is embedded in the heat dissipation holes; there are two symmetrical support legs 102 on the outer wall of the housing 101 (the support legs 102 are inclined outward to improve support stability), and each support leg 102 has a braked universal wheel installed at the bottom end (away from the end of the housing 101). Two braked universal wheels are symmetrically installed in the area at the bottom of the housing 101 away from the support legs 102. The four braked universal wheels form a rectangular support system, which, together with the housing 101, forms a movable carrier platform, enabling the movable component 1 to carry the gas cylinder for position transfer.

[0024] In this embodiment, as Figure 2 As shown, two fixed tubes 103 are symmetrically installed on the top of the housing 101. The inner wall of the fixed tube 103 slides with the push handle 104 to form a telescopic structure. Several threaded holes are evenly distributed axially on the push handle 104. A radial connection hole is opened in the top area of ​​the fixed tube 103. The hand-tightening bolt passes through the connection hole of the fixed tube 103 and the selected threaded hole on the push handle 104 in sequence. The relative position is locked by thread engagement. By selecting threaded holes of different heights, the push handle 104 can be continuously adjusted within a certain range to adapt to the force requirements of operators of different heights. The operator holds the push handle 104 and applies horizontal thrust. The tooling moves smoothly as a whole through the four braked universal caster system at the bottom of the housing 101.

[0025] In this embodiment, as Figure 2 As shown, two first slide rods 107 are symmetrically installed on the bottom of the fixed plate 106. The top of the box 101 is provided with a sliding hole corresponding to the first slide rod 107. The first slide rod 107 passes through the sliding hole and forms a sliding fit with the box 101. When the electric push rod 105 is started, its telescopic end drives the fixed plate 106 to move vertically, and synchronously drives the two first slide rods 107 to slide along the axial direction of the sliding hole. The symmetrical layout of the double slide rods forms an over-constraint guide system, which suppresses the radial displacement of the fixed plate 106 and improves the rigidity of the lifting process. The vertical displacement of the fixed plate 106 is synchronously transmitted to the arc plate 109 and the bottom plate 1010 through the mounting bracket 108 to realize the clamping and lifting of the gas cylinder. Three telescopic protective covers are installed between the bottom of the fixed plate 106 and the top of the box 101. Protective covers are also fitted around the two first slide rods 107 and the electric push rod 105.

[0026] In this embodiment, as Figure 1 and Figure 3As shown, the top of the movable block 501 is provided with an insertion block 502, and the top of the connecting block 3 is provided with an insertion hole that matches the insertion block 502. The top of the insertion block 502 is provided with a slot, which is constructed as an interface for inserting an external insertion block and is used to limit the displacement of the movable block 501. A handle 503 is installed on one side of the movable block 501. Two symmetrically distributed second slide rods 504 are slidably installed through one side of the movable block 501, and the ends of the second slide rods 504 are connected to the clamping plate 505. When placing a gas cylinder onto the fixture, hold the handle 503 and move the limiting component 5 upwards so that the insert block 502 is inserted into the socket of the connecting block 3 until the slot protrudes from the top surface of the connecting block 3; insert the external plug into the slot to form an axial constraint on the moving block 501, and place the gas cylinder vertically on the base plate 1010 (at this time, the clamping plate 505 is in the avoidance position). After releasing the constraint of the plug on the slot, move the limiting component 5 downwards so that its bottom contacts the support block 4; rotate the anti-slip knob at the end of the threaded rod 506 to drive the clamping plate 505 to move axially along the second slide rod 504 until the inner arc surface of the clamping plate 505 contacts the outer wall of the gas cylinder, thus limiting the gas cylinder.

[0027] The specific operating procedure of this utility is as follows: First, the operator adjusts the push handle 104 to a suitable height within the fixed tube 103 according to their own height requirements and locks it by hand-tightening the bolt.

[0028] When moving gas cylinders, first adjust the position of support block 4 according to the height of the gas cylinder: loosen the bolts of support block 4, slide support block 4 along guide rod 2, and insert the bolts into the corresponding round holes of guide rod 2 and the connecting holes of support block 4 to lock them. At this time, the operator holds handle 503 and slides the limiting component 5 upward along guide rod 2, so that the insert block 502 is inserted into the insertion hole at the top of connecting block 3 until the slot is exposed, and then inserts the external insert block into the slot and locks it, so that the limiting component 5 is in a high-position avoidance state.

[0029] Next, the gas cylinder is moved onto the base plate 1010 manually or by other lifting devices. The plug block is then pulled out to release the limit. The limit component 5 slides down along the guide rod 2 until the bottom of the moving block 501 contacts the top surface of the support block 4 for positioning. The anti-slip knob at the end of the threaded rod 506 is rotated to drive the clamping plate 505 forward along the symmetrically distributed second sliding rod 504, so that the M-shaped clamping surface fits against the outer wall of the gas cylinder. At the same time, the arc plate 109 forms opposing support on the other side of the gas cylinder.

[0030] Next, the electric push rod 105 is activated, and its telescopic end pushes the fixed plate 106 vertically upward. At this time, the double first slide rods 107 at the bottom of the fixed plate 106 slide synchronously along the sliding holes at the top of the housing 101, suppressing radial displacement during the lifting process; the displacement of the fixed plate 106 synchronously drives the arc plate 109 and the base plate 1010 to lift the gas cylinder through the mounting bracket 108. After the gas cylinder is raised to the target height, the operator holds the push lever 104, which has been pre-adjusted to the height, and applies a horizontal pushing force. The tooling is moved to the target position by the four symmetrically distributed braked casters at the bottom of the housing 101.

[0031] Upon arrival, the electric push rod 105 retracts, and the gas cylinder moves down and lands with the base plate 1010. Reversing the anti-slip knob causes the clamping plate 505 to retract and release the workpiece. The handle 503 pushes the limiting component 5 up until the insert block 502 is inserted into the socket of the connecting block 3 and then inserted into the plug block to lock it, completing the gas cylinder unloading cycle.

[0032] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
