Description

Technical Field

[0001] This utility model relates to the field of transfer bracket technology, specifically to a bracket suitable for the safe transfer of liquid chlorine cylinders. Background Technology

[0002] Liquid chlorine cylinders are high-pressure containers used for storing and transporting liquid chlorine. They are typically made of stainless steel (such as 304 or 316L) or corrosion-resistant carbon steel to resist the strong oxidizing and corrosive properties of chlorine gas.

[0003] In the context of small liquid chlorine cylinders or short-distance transportation, horizontal transfer supports are widely used due to their simple structure and convenient loading and unloading. In the existing technology, horizontal supports usually include a base, on which two sets (two in each set) of support rollers are arranged at intervals along the axial direction of the cylinder to form a four-point support structure. Rubber pads are laid at the contact points between the rollers and the cylinder to achieve anti-slip and shockproof effects.

[0004] However, the rollers on the existing horizontal support can only provide lateral support (i.e., the curved surface of the liquid chlorine cylinder), while the displacement of the cylinder along the axial direction (i.e., the direction between the valve end and the bottom end) is limited only by the friction between the rubber pad and the liquid chlorine cylinder. When the vehicle bumps or brakes suddenly, the cylinder is prone to move towards the valve end and the bottom end due to inertia, causing the valve to collide with the end of the support and the bottom to rub against the base. Therefore, it may cause damage to the valve or damage to the surface of the cylinder. In severe cases, the cylinder may leak due to tipping or collision, affecting the safety of transportation. Utility Model Content

[0005] In view of this, the present invention provides a bracket suitable for the safe transport of liquid chlorine cylinders. It can effectively limit the axial movement of liquid chlorine cylinders by setting a fixed frame, flexible restraints or arc-shaped limiting grooves in the base, avoiding collisions and friction caused by bumps and sudden braking during transportation, protecting the valve and cylinder surface, reducing the risk of leakage, and improving transportation safety.

[0006] To solve the above-mentioned technical problems, this utility model provides a bracket suitable for the safe transfer of liquid chlorine cylinders, including a base. The base is a frame-shaped bottom plate formed by four fixed plates connected vertically at their ends. A set of support mechanisms is provided on the upper part of the base. The support mechanisms include four sets of support rollers arranged in a rectangular array on the upper part of the base. The liquid chlorine cylinder is placed on the four sets of support rollers. The arc-shaped surface of the liquid chlorine cylinder is placed on the upper part of the four sets of support rollers. A reinforcing ring is provided on the outer side wall of the liquid chlorine cylinder.

[0007] A fixing frame is installed on the upper part of the base and on both sides of the arc-shaped outer wall of the liquid chlorine cylinder. The fixing frame consists of two columns and a crossbeam. Constraints are symmetrically arranged on the two fixing frames. The constraints are flexible and can be made of chains to limit the movement of the liquid chlorine cylinder along the axial direction.

[0008] One end of the constraint is hinged to the upper part of one of the fixed frames. The hinge on the upper part of the fixed frame uses a support buckle with an arched structure. The other end of the constraint is detachably connected to the upper part of another fixed frame. The upper part of the other fixed frame uses a limiting post with a square column structure to fix the constraint and improve the limiting effect on the liquid chlorine cylinder.

[0009] The constraint is set as a flexible constraint, which uses a chain. One of the chain links is sleeved on the outer wall of the limiting post. The chain link can be adjusted to fit the limiting post according to different sizes of liquid chlorine cylinders, and the liquid chlorine cylinder can be quickly fixed or loosened.

[0010] A rubber sleeve is installed on the outer wall of the chain. The rubber sleeve is inserted through the detachable end of the chain and covers the contact area between the chain and the liquid chlorine cylinder to prevent the outer wall of the liquid chlorine cylinder from being damaged due to continuous friction between the chain and the liquid chlorine cylinder.

[0011] The system includes a base, which is a frame-shaped base plate formed by four fixed plates connected vertically at their ends. A set of support mechanisms is set on the upper part of the base, on which a liquid chlorine cylinder is placed. Reinforcing rings are symmetrically arranged on the outer wall of the liquid chlorine cylinder. The support mechanism includes a support frame symmetrically arranged on the upper part of the base. The cross-section of the support frame is set as an arc structure, and a limiting groove adapted to the reinforcing ring is opened on the inner side wall of the support frame.

[0012] The limiting groove is designed with an arc shape, and the reinforcing ring is placed in the corresponding limiting groove to achieve axial positioning. The arc of the limiting groove is adapted to the outer circle of the reinforcing ring to distribute the force evenly, reduce local stress concentration, and reduce wear and deformation of the cylinder surface.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] 1. Axial limiting to prevent movement and collision: By setting fixed frames and restraints on both sides of the base, or by opening arc-shaped limiting grooves in the support frame, the movement of liquid chlorine cylinders along the axial direction (valve end and bottom end of the cylinder) can be effectively limited. This avoids collisions or friction between the liquid chlorine cylinder and the end of the support due to vehicle bumps, sudden braking, etc. during transportation, thereby protecting the valve and the surface of the liquid chlorine cylinder from damage, reducing the risk of leakage, and significantly improving transportation safety.

[0015] 2. Flexible constraints and surface contact reduce local stress concentration: The flexible constraint component can fit tightly against the side of the reinforcing ring of the liquid chlorine cylinder to form surface contact. Compared with the point or line contact of rigid constraints, it can evenly distribute the load and avoid excessive local stress that could cause deformation or wear of the liquid chlorine cylinder. The arc-shaped limiting groove can evenly transmit the impact force, avoid structural damage caused by local pressure concentration, and extend the service life of the cylinder.

[0016] 3. Buffering, shock absorption, and wear protection: The rubber sleeve on the outside of the restraint covers the contact area with the cylinder. Utilizing the low coefficient of friction and elastic deformation of rubber, friction loss is reduced and impact energy is absorbed, reducing scratches, dents, and other wear on the cylinder surface. At the same time, it buffers the instantaneous impact force of dynamic loads on the cylinder. The arc-shaped structure of the support frame is adapted to the outer contour of the cylinder, increasing the contact area, reducing pressure, and avoiding hard squeezing that could damage the anti-corrosion coating or the metal body of the cylinder surface.

[0017] 4. Convenient loading and unloading and strong adaptability: The constraint is hinged at one end and detachably connected at the other end (such as a chain link with a limiting post), which can quickly adjust the constraint length to adapt to different sizes of cylinders, realize convenient fixing and loosening operations, improve loading and unloading efficiency, and the smooth surface and depth design of the limiting groove (covering at least half the thickness of the reinforcing ring) restricts the cylinder's vertical movement while allowing sliding during slight vibration, reducing frictional resistance and facilitating cylinder positioning and installation.

[0018] 5. Dual limiting and structural reinforcement: Example 3 combines flexible constraint components and limiting groove structure to form dual axial limiting of the steel cylinder reinforcing ring (constraint components block the side, and limiting groove fixes the axial position), further improving the stability of transportation. The mounting groove of the base is adapted to forklift forks, which facilitates overall handling and optimizes the practicality and reliability of the bracket. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0027] Example 1;

[0028] A bracket suitable for the safe transport of liquid chlorine cylinders includes a base 101. The base 101 is a frame-shaped base plate formed by four fixed plates vertically connected at their ends. A support mechanism is provided on the upper part of the base 101. The support mechanism includes four sets of support rollers arranged in a rectangular array on the upper part of the base 101. The liquid chlorine cylinder is placed on the four sets of support rollers. The arc-shaped surface of the liquid chlorine cylinder is placed on the upper part of the four sets of support rollers. A reinforcing ring is provided on the outer side wall of the liquid chlorine cylinder. The above contents are all prior art and therefore do not need to be described in detail.

[0029] like Figure 1 , 2 As shown in Figure 3: A fixing frame 102 is provided on the upper part of the base 101 and on both sides of the arc-shaped outer wall of the liquid chlorine cylinder. The fixing frame 102 consists of two columns and a crossbeam parallel to the base 101. Two constraint members are used on the two fixing frames 102 to limit the axial direction of the liquid chlorine cylinder. That is, when the liquid chlorine cylinder is transported by vehicle, when the vehicle is bumped, the valve side and bottom side of the liquid chlorine cylinder can be indirectly limited by restraining the reinforcing ring on the liquid chlorine cylinder, so as to prevent the liquid chlorine cylinder from moving along the axial direction due to vehicle bumps or other reasons.

[0030] It is worth mentioning that the restraint uses chains 103. After the two chains 103 are tied to the outer wall of the liquid chlorine cylinder, each chain 103 can limit the liquid chlorine cylinder regardless of which side of the reinforcing ring it contacts (i.e., the chain 103 can abut against both side walls of the reinforcing ring). When the liquid chlorine cylinder moves along the axis, the two chains 103 block the side of the reinforcing ring and prevent the liquid chlorine cylinder from moving along the axis.

[0031] As a flexible constraint, chain 103 can closely fit the side of the arc-shaped reinforcing ring of the liquid chlorine cylinder, avoiding local stress concentration caused by incomplete shape matching (if a rigid constraint is used, only line contact or point contact can be formed, which will lead to an increase in local stress, while the flexible constraint forms surface contact or near-surface contact. By fitting the side of the reinforcing ring, a continuous arc-shaped contact area is formed, thereby reducing local stress).

[0032] Using chain 103 can also accommodate the slight displacement and deformation of liquid chlorine cylinders caused by vibration and bumps during transportation, reducing hard friction or squeezing damage to the outer wall and reinforcing ring of the cylinder, and preventing damage to the liquid chlorine cylinder.

[0033] like Figure 2 , 3 As shown in Figure 4: The chain link at one end of the chain 103 is hinged to the support buckle 104. The support buckle 104 is fixedly connected to the upper part of the fixing frame 102. The support buckle 104 has an arched structure, which can distribute the load and reduce stress concentration. It can convert the tension or pressure transmitted by the chain 103 into axial pressure along the arch axis. That is, the external load (such as the tension of the chain 103) is distributed to the arch foot (i.e. the connection between the support buckle 104 and the fixing frame 102) through the curved surface of the arch. This allows the material of the support buckle 104 to mainly bear axial compressive stress, rather than bending or shear stress, reducing the risk of deformation and breakage of the support buckle 104.

[0034] The arched curved structure allows force to be transmitted evenly along the arc, unlike right-angle connections which are prone to generating excessive pressure at a certain point or line. The chain 103 is hinged to the arched support buckle 104, which can transmit tension along the arc of the arch, allowing the force to be distributed more evenly and reducing damage to the connection due to force concentration.

[0035] The other end of the chain 103 is fitted onto the outer wall of the limiting post 105. The limiting post 105 is a square column structure with four planes. When one of the chain links of the chain 103 is fitted onto the limiting post 105, the edges and planes can hold the chain link in place, preventing the chain link from sliding and preventing the fixing point from loosening.

[0036] The four vertical planes of the limiting post 105 are provided with anti-slip textures, which can further prevent the chain links from falling off.

[0037] like Figure 1 , 2 As shown: A rubber sleeve 106 is fitted on the outer wall of the chain 103. The rubber sleeve 106 needs to cover the contact area between the chain 103 and the liquid chlorine cylinder and the reinforcing ring. By utilizing the low coefficient of friction and high wear resistance of rubber, friction loss is significantly reduced, and damage such as scratches and pits on the surface of the cylinder is avoided due to continuous friction.

[0038] During transportation, dynamic loads such as bumps and sudden braking will cause the chain 103 to exert an instantaneous impact force on the liquid chlorine cylinder. The elastic deformation capability of the rubber sleeve 106 can absorb some of the kinetic energy, slow down the transmission rate of the impact force, and prevent damage to the surface of the liquid chlorine cylinder and the reinforcing ring.

[0039] Example 2;

[0040] The difference from Embodiment 1 is that it includes a base 101, which is a frame-shaped base plate formed by four fixed plates connected vertically at their ends. A set of support mechanisms is provided on the upper part of the base 101, and a liquid chlorine cylinder is placed on the support mechanisms. Reinforcing rings are symmetrically arranged on the outer side wall of the liquid chlorine cylinder.

[0041] like Figure 1 , 5 As shown: The support mechanism includes a support frame 201 symmetrically arranged on the upper part of the base 101. The cross-section of the support frame 201 is set as an arc structure. The arc structure is adapted to the outer circle contour of the liquid chlorine cylinder. It can evenly distribute the weight of the cylinder and the load (such as vibration and impact) during transportation to the base 101 along the arc, avoiding damage to the shell of the liquid chlorine cylinder caused by the mismatch of the shape of the traditional right angle or flat structure.

[0042] The curved surface support characteristic of the arc structure can convert vertical loads into tangential pressure along the arc surface, and reduce the occurrence of deformation or breakage by utilizing the load-bearing capacity of the support frame 201.

[0043] The inner side of the support frame 201 is attached to the arc-shaped outer wall of the cylinder, forming a large area of ​​curved surface contact. Compared with flat support, the contact area is increased, thereby reducing the pressure and protecting the surface of the liquid chlorine cylinder, avoiding damage to the liquid chlorine cylinder due to hard compression.

[0044] The symmetrically arranged support frame 201, together with the two reinforcing rings of the liquid chlorine cylinder, forms a two-way constraint, which stabilizes and supports the cylinder while limiting the back-and-forth swaying of the liquid chlorine cylinder (i.e., the liquid chlorine cylinder moves towards the valve end or towards the bottom of the cylinder), thus improving the stability during the transfer process.

[0045] like Figure 5 As shown: The inner wall of the support frame 201 is provided with a limiting groove 202 that is adapted to the reinforcing ring. The limiting groove 202 is set with an arc-shaped structure so that the reinforcing ring forms a surface contact after being placed in it. The impact force during transportation will be evenly distributed to the entire contact area, avoiding excessive local pressure that could cause deformation of the reinforcing ring or wear on the surface of the liquid chlorine cylinder. The reinforcing ring is placed in the corresponding limiting groove 202 to achieve axial positioning.

[0046] The surface of the limiting groove 202 is designed to be smooth, which reduces the frictional force of sliding during vibration, preventing the coating on the surface of the liquid chlorine cylinder from being worn away or the metal from being scratched. At the same time, the uniform force on the smooth surface will prevent the reinforcing ring from being pressed into a pit, thus protecting the structural strength of the liquid chlorine cylinder and extending its service life.

[0047] The depth of the limiting groove 202 is at least half the thickness of the reinforcing ring. After the reinforcing ring is placed in the limiting groove 202, it can effectively restrict the movement of the cylinder in the vertical direction (i.e., in the direction perpendicular to the upper surface of the base 101), and further prevent the liquid chlorine cylinder from falling out of the limiting groove 202 due to slight displacement caused by vehicle bumps.

[0048] like Figure 1 , 5 As shown: Reinforcing ribs 203 are symmetrically arranged between the arc-shaped outer wall of the support frame 201 and the base 101. The upper end of the reinforcing ribs 203 is inclined towards the axis of the support frame 201. The inclined structure can improve the support stability and impact resistance of the reinforcing ribs 203 to the support frame 201.

[0049] like Figure 5 As shown: Two of the fixing plates that make up the base 101 have mounting slots 204 through them on one vertical surface, so that the forklift forks can be inserted into the mounting slots 204 to lift the base 101 for loading.

[0050] Example 3;

[0051] The difference from Embodiment 1 is that, in this embodiment, as... Figure 1 , 4 As shown in Figure 5: Using the support mechanism in Embodiment 2, and in conjunction with the chain 103 in Embodiment 1, which is hinged at one end and detachably connected to the fixed frame 102 at the other end, after the two reinforcing rings on the liquid chlorine cylinder are placed in the limiting groove 202, a suitable chain link at one end of the chain 103 (i.e., according to the size of the liquid chlorine cylinder, one chain link is first used to fit on the limiting post 105 so that the chain 103 just binds the liquid chlorine cylinder) is fitted onto the limiting post 105, further limiting the side wall of the reinforcing rings. This can further prevent the liquid chlorine cylinder from easily moving towards the valve end and the bottom end due to inertia when the vehicle bumps or brakes suddenly. Therefore, the safety and stability of the liquid chlorine cylinder during transportation can be improved.

[0052] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0053] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
