The weight of a single blasting cylinder is 90kg-130kg, and it usually needs two workers to carry together, which makes the empty blasting cylinder too inconvenient to load liquid carbon dioxide. Therefore, in order to solve the above problems, the blasting cylinder loading fixing structure is proposed. UTILITY MODEL CONTENTS

[0028] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0029] like Figures 1 to 4As shown, a blasting cartridge loading fixing structure 10 comprises a support frame 100 for supporting a blasting cartridge 20 and two clamping assemblies 200 arranged on the same end of the support frame 100, each clamping assembly 200 comprising a rotating frame 210, a screw rod 220, a pressing block 230 and a clamping hook 240, one end of the rotating frame 210 is rotatably arranged on the support frame 100, the clamping hook 240 is rotatably arranged on the other end of the rotating frame 210, the screw rod 220 is screwed with the rotating frame 210, and the pressing block 230 is rotatably arranged on the end of the screw rod 220, when the rotating frame 210 is forced to rotate, the clamping hook 240 is clamped with the support frame 100, and when the screw rod 220 is forced to rotate, the pressing block 230 is pressed against the blasting cartridge 20 on the support frame 100.

[0030] It should be noted that the support frame 100 has a frame-like structure, and the blasting cylinder 20 can slide back and forth on the support frame 100. Two clamping assemblies 200 are installed at the same end of the support frame 100, and there is a gap between the two clamping assemblies 200. It should be noted that the end of the support frame 100 away from the clamping assembly 200 can be connected to a crane device to realize automatic loading and unloading of the blasting cylinder 20. Furthermore, after the blasting cylinder 20 is placed on the support frame 100, it can be pushed to slide closer to or away from the clamping assembly 200. Furthermore, an external force is applied to the hook 240 to disengage it from the support frame 100, and then an external force is applied to the rotating frame 210, causing the rotating frame 210 to drive the screw 220, the pressure block 230, and the hook 240 to rotate as a whole relative to the support frame 100. In this way, the blasting cylinder 20 can be pushed closer to the rotating frame 210. Then, a reverse thrust is applied to the rotating frame 210, causing the rotating frame 210 to drive the screw 220, the pressing block 230, and the hook 240 to rotate in the opposite direction relative to the support frame 100. Then, the hook 240 is clamped to the support frame 100. Finally, a torque is applied to the screw 220, causing the screw 220 to drive the pressing block 230 closer to the support frame 100, thereby making the pressing block 230 reliably press and fix the blasting cylinder 20 that has been pushed close to the rotating frame 210. Finally, the blasting cylinder 20 can be filled with liquid carbon dioxide by a high-pressure pump. Furthermore, after the blasting cylinder 20 is filled, the screw 220 is first rotated to loosen the pressure block 230 from the blasting cylinder 20. Then, the hook 240 is rotated to disengage from the support frame 100. Finally, the rotating frame 210 is rotated to cause the screw 220, pressure block 230, and hook 240 to rotate relative to the support frame 100 as a whole. In this way, the blasting cylinder 20 can be pushed again to slide away from the clamping assembly 200. Compared with the fixed clamping structure in the prior art, the rotating frame 210 structure proposed in this application does not require workers to move the blasting cylinder 20. Only a pushing force needs to be applied to the blasting cylinder 20 to make it slide on the support frame 100, which is convenient for operation. Secondly, since no workers need to manually move it, the risk of the blasting cylinder 20 accidentally falling during the handling process is avoided, making it safer to use.

[0031] In one embodiment, the rotating frame 210 has a U-shaped structure. It should be noted that the rotating frame 210 is configured as a gantry-like U-shaped structure, facilitating the rotatable installation of one end of the rotating frame 210 with the support frame 100, while the other end of the rotating frame 210 drives the hook 240 to engage and fix with the support frame 100. Furthermore, when the screw 220 drives the pressure block 230 to press against the blasting cylinder 20, it ensures that the pressure block 230 applies a balanced clamping force to the blasting cylinder 20.

[0032] like Figure 1 and Figure 4As shown, in one embodiment, the clamping assembly 200 further includes a rotating base 250, which is welded to the side wall of the support frame 100, and one end of the rotating frame 210 is rotatably connected to the rotating base 250.

[0033] It should be noted that, in order to enable the rotating frame 210 to rotate stably relative to the support frame 100, a rotating base 250 is welded and fixed to the side wall of one end of the support frame 100. The rotating base 250 has a shaft that passes through the rotating frame 210, so that the rotating frame 210 can rotate relative to the shaft of the rotating base 250, thereby enabling the rotating frame 210 to rotate relative to the rotating base 250.

[0034] like Figure 4 As shown, in one embodiment, a waist-shaped hole 211 is provided on one end of the rotating frame 210, and part of the structure of the rotating seat 250 passes through the waist-shaped hole 211.

[0035] It should be noted that, since the hook 240 needs to be hooked and fixed to the support frame 100, in order for the screw 220 to drive the pressing block 230 to press the blasting cylinder 20 in a balanced manner, the hole through which the shaft of the rotating base 250 passes into the rotating frame 210 is set as an oblong hole 211. In this way, when the hook 240 is hooked and fixed to the support frame 100, the rotating frame 210 remains balanced.

[0036] like Figure 2 and Figure 4 As shown, in one embodiment, a crossbar 300 is provided on the support frame 100, and a hook 240 is used to engage with the crossbar 300.

[0037] It should be noted that in order to ensure that the hook 240 can be stably hooked and fixed to the support frame 100, a crossbar 300 is welded and fixed to the support frame 100 in the horizontal direction, so that the hook 240 can be fixed to the support frame 100 by hooking the crossbar 300.

[0038] like Figure 3 As shown, in one embodiment, the clamping assembly 200 further includes a spring 260, which is connected to the rotating frame 210 and the hook 240 respectively. The spring 260 is used to drive the hook 240 to engage the crossbar 300.

[0039] It should be noted that the spring 260 pulls the hook 240, causing the hook 240 to tend to hook the crossbar 300 in its natural state, thus reliably locking the hook 240 to the crossbar 300. When it is necessary to separate the hook 240 from the crossbar 300, an external force needs to be applied to rotate the hook 240, causing the spring 260 to be stretched.

[0040] like Figure 4As shown, in one embodiment, the hook 240 includes a body 241, a rotating shaft 242 and two protrusions 243. The rotating shaft 242 is disposed on the body 241 and passes through the rotating frame 210. The two protrusions 243 are respectively disposed on both sides of the body 241. A spring 260 is wound around the rotating frame 210, and the two ends of the spring 260 are respectively connected to the two protrusions 243.

[0041] It should be noted that the main body 241 is provided with barbs, and the rotating shaft 242 passes through the rotating frame 210, so that the main body 241 can rotate relative to the rotating shaft 242. Two protrusions 243 are respectively provided on opposite sides of the main body 241, and the two ends of the spring 260 are respectively connected to the two protrusions 243. The spring 260 is wound around the outer side wall of the rotating frame 210. Thus, under the elastic tension of the spring 260, the main body 241 tends to hook the crossbar 300.

[0042] like Figures 2 to 4 As shown, in one embodiment, the main body 241 is also provided with a fastener 244, which is used to make the main body 241 rotate relative to the rotating shaft 242 when subjected to force, thereby stretching the spring 260.

[0043] It should be noted that, in order to facilitate the worker to apply external force to the hook 240 so that the hook 240 can disengage from the crossbar 300, a buckle 244 is provided on the body 241. By applying external force to the buckle 244, the barb of the body 241 can be quickly disengaged from the crossbar 300.

[0044] like Figure 4 As shown, in one embodiment, the pressing block 230 includes a rotary joint 231 and an arc-shaped block 232. The rotary joint 231 is sleeved on the screw 220, and the arc-shaped block 232 is disposed on the rotary joint 231 so that the rotary joint 231 can rotate relative to the screw 220. An arc-shaped groove 2321 adapted to the outer wall of the blasting cylinder 20 is provided on the side of the arc-shaped block 232 away from the rotary joint 231.

[0045] It should be noted that the arc-shaped block 232, which directly presses against the blasting cylinder 20, is prone to deformation and wear after prolonged use. Therefore, the arc-shaped block 232 is designed as a detachable installation structure. Secondly, in order to ensure that the pressure block 230 can reliably press the blasting cylinder 20, the pressure block 230 is designed as a structure that rotates relative to the screw 220. Specifically, the screw 220 passes through the screw joint 231, and the arc-shaped block 232 is locked and fixed to the screw joint 231 by screws, making the arc-shaped block 232 detachable relative to the screw joint 231. Furthermore, the arc-shaped groove 2321 opened on the arc-shaped block 232 is adapted to the outer wall of the blasting cylinder 20, thus ensuring that the arc-shaped block 232 can stably press and fix the blasting cylinder 20.

[0046] Furthermore, such asFigure 4 As shown, in one embodiment, a buffer pad 233 is also provided on the inner sidewall of the arc groove 2321.

[0047] It should be noted that the buffer pad 233 is made of silicone. The buffer pad 233 is attached to the inner wall of the arc groove 2321. The buffer pad 233 can fully contact the outer wall of the blasting tube 20, thereby fully increasing the friction between the buffer pad 233 and the blasting tube 20, so that the blasting tube 20 is reliably pressed and fixed.

[0048] like Figures 1 to 4 As shown, in one embodiment, a handwheel 270 is provided at the top of the screw 220. In this way, the handwheel 270 facilitates the worker to apply torque to the screw 220.

[0049] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
