Description

Technical Field

[0001] The invention relates to the technical field of fire fighting equipment, and in particular to an auxiliary water pipe fixing device for a fire fighting truck. Background Art

[0002] A fire truck, also known as a fire truck, is a vehicle that is designed and manufactured according to needs and is suitable for firefighters to ride, equipped with various fire-fighting equipment or fire extinguishing agents, and is used by fire forces to extinguish fires, assist in firefighting, or for firefighting rescue. When firefighters drive a fire truck to put out a fire, the fire truck is often parked in a relatively safe area and connected to a fire hydrant. The firefighters pull the fire hose to quickly approach the fire source, and the fire truck pressurizes the water and sprays it out. The impact force of the high-pressure water sprayed from the water pipe is borne by the firefighters.

[0003] Currently, there is a patent (Announcement No.: CN107998556B) and a fire truck water pipe fixing device. This patent fixes the head of the water pipe on the fire truck, reduces the impact of the water column on the firefighter holding the water gun, and enables the firefighter to save more energy. It should be noted that the firefighter needs to quickly drag the water pipe to a position close to the fire extinguishing position, and then open the water valve to use high-pressure water flow to extinguish the fire. The above device is difficult to carry with one hand, which will delay the time. At the same time, it is unclear how its height is adapted to the height of the firefighter. It should also be noted that the firefighter needs to adjust the position of the water pipe according to the fire. For example, when the fire subsides, the water pipe head needs to be quickly pushed forward, and the above patent is obviously not conducive to the movement of firefighters. It is impossible to quickly push forward when the fire subsides to further suppress the fire.

[0004] Therefore, it is necessary to provide an auxiliary water pipe fixing device for a fire-fighting fire truck to solve the above technical problems. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an auxiliary water pipe fixing device for fire-fighting fire trucks, which utilizes the stability of a 60° triangle and the gravity suppression of the entire device by the weight of the firefighters themselves, thereby effectively resisting the impact force of the rapid spraying of water and greatly reducing the physical exertion of firefighters under long-term continuous high-pressure water flow fire extinguishing conditions.

DETAILED DESCRIPTION

[0037] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. 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.

[0038] Embodiment 1

[0039] The present invention provides an auxiliary water pipe fixing device for a fire-fighting truck, comprising a left frame 1, a right frame 2 and a folding component 3. The left frame 1 and the right frame 2 are folded by the folding component 3. The folding component 3 comprises a left expansion rod 31, a right expansion rod 33 and a folding axis 32. The left expansion rod 31 is fixed on the side wall of the counterweight seat 13 of the left frame 1, and the right expansion rod 33 is fixed on the side wall of the counterweight seat 13 of the right frame 2. The left expansion rod 31 and the right expansion rod 33 are connected by the folding axis 32. The left expansion rod 31 and the right expansion rod 33 fold the left frame 1 and the right frame 2 by the folding axis 32.

[0040] The folding component 3 adopts a cylindrical rotating shaft, which is formed by two or more cylinders embedded in each other. The structure allows the cylindrical shaft to achieve 360° rotation. In this device, the left expansion rod 31 and the right expansion rod 33 are folded by the folding axis 32.

[0041] The working principle of the cylindrical shaft is based on its simple mechanical structure. The angle is adjusted by the mutual nesting and rotation of cylindrical parts. When rotation is required, the inner cylinder rotates relative to the outer cylinder, thereby changing the overall direction or position.

[0042] The main body of the left frame 1 is composed of a counterweight seat 13 connected to a vertical rod 12. The center of gravity of the device is lowered by the counterweight seat 13. The side wall of the counterweight seat 13 is provided with a groove for installing a storage type auxiliary support component 14. The main body of the auxiliary support component 14 is stored in the groove.

[0043] The auxiliary support rod 143 of the auxiliary support component 14 is connected to the top of the groove on the counterweight seat 13 through the expansion axis 141. The auxiliary support rod 143 is rotated and expanded with the expansion axis 141 as a circle. A rotating reinforcing rod 144 is connected to the side wall of the auxiliary support rod 143 corresponding to the groove through a hinge. A supporting hole 142 for nesting the reinforcing rod 144 is opened on the symmetrical side wall of the counterweight seat 13 with the groove. By nesting the reinforcing rod 144 in the supporting hole 142 on the side wall of the counterweight seat 13, the expansion angle of the auxiliary support rod 143 and the counterweight seat 13 is strengthened and fixed.

[0044] A stabilizing rod for stepping on is installed on the side wall at the bottom of the auxiliary support rod 143. The stabilizing rod is cylindrical. Firefighters wear fire boots. The soles of the fire boots have arched anti-skid grooves. The protective grooves can engage with the cylindrical stabilizing column. An inclined support plate 146 inclined upward is provided at the bottom of the auxiliary support rod 143. A moving wheel 145 is installed inside the inclined support plate 146. Either the moving wheel 145 or the auxiliary support rod 143 touches the ground.

[0045] The auxiliary support rod 143 and the counterweight seat 13 touch the ground at the same time. The bottom surface of the counterweight seat 13 is provided with an inclined surface, and is inclined upward toward the side with the auxiliary support component 14. The bottom surface of the auxiliary support rod 143 is provided with a flat surface, and it and the inclined surface of the counterweight seat 13 touch the ground at the same time. The angles between the auxiliary support rod 143, the counterweight seat 13 and the ground are all 60°, and each internal angle of the equilateral triangle is 60 degrees. This triangle is very stable in structure.

[0046] The auxiliary support rod 143 is unfolded through the unfolding shaft 141, and the reinforcing rod 144 is unfolded by the hinge and nested in the corresponding support hole 142, and the counterweight seat 13 and the auxiliary support rod 143 are unfolded at 60 degrees, and the corresponding fixing component 4 of the water pipe is fixed, and the stabilizing rod of the left frame 1 and the stabilizing rod of the right frame 2 are stepped on by both feet respectively, and the handrails 11 on the vertical pole 12 of the left frame 1 and the handrails 11 of the vertical pole 12 of the right frame 2 are held with both hands. The stability of the 60° triangle and the gravity suppression of the entire device are formed by the weight of the firefighters themselves, which can effectively resist the impact force of the rapid spraying of water and greatly reduce the physical exertion of firefighters in the state of long-term continuous high-pressure water fire fighting.

[0047] The structure of the right frame 2 is symmetrical and identical to that of the left frame 1;

[0048] A fixing assembly 4 for fixing the water pipe is installed between the left frame 1 and the right frame 2.

[0049] The fixing assembly 4 includes a left fixing ring 46, a right fixing ring 45 and an annular component;

[0050] The left fixing ring 46 is fixed to the upright pole 12 of the left frame 1, and the right fixing ring 45 is fixed to the upright pole 12 of the right frame 2;

[0051] The annular component is divided into an upper ring 42 and a lower ring 43. The upper ring 42 and the lower ring 43 are connected by a hinge on one side to form an open-close type. The other side of the upper ring 42 and the lower ring 43 is closed and locked by a movable clamping component 47. By opening the upper ring 42 and the lower ring 43, the pipe mouth of the fire hose is clamped between the upper ring 42 and the lower ring 43, and then the upper ring 42 is closed corresponding to the lower ring 43, and the closed locking is completed by the movable clamping component 47;

[0052] The lower ring 43 is symmetrically provided with fixing rods 44 on both sides. The two groups of fixing rods 44 are respectively nested in the insertion holes 461 of the left fixing ring 46 and the insertion holes 461 of the right fixing ring 45 , and the annular component is fixed by the two groups of fixing rods 44 .

[0053] The structure of the left fixing ring 46 is symmetrical to that of the right fixing ring 45;

[0054] A rotatable angle seat 462 is provided on one side of the left fixed ring 46, and a stud 465 is provided on one end of the angle seat 462;

[0055] The hoop 463 of the left fixing ring 46 is fastened to the vertical pole 12 of the left frame 1, and the outer wall of the hoop 463 is provided with an extension column having a screw hole 464 adapted to the stud 465. The stud 465 of the angle seat 462 is screwed into the extension column screw hole 464 on the hoop 463 of the left fixing ring 46, and the angle of the angle seat 462 is adjusted by rotating the thread, and the angle of the angle seat 462 is adjusted by rotating the stud 465 in the threaded hole.

[0056] An adjustment plate 41 is installed on the top of the upper ring 42. Pushing the adjustment plate 41 causes the angle of the annular component to rotate around the angle seat 462. The two groups of fixed rods 44 push the angle seat 462 of the left fixed ring 46 and the angle seat 462 of the right fixed ring 45 to rotate synchronously, and the stud 465 rotates in the threaded hole.

[0057] By pushing the adjustment plate 41, the angle of the annular component rotates around the angle seat 462, and the two sets of fixed rods 44 of the lower ring 43 push the angle seat 462 of the left fixed ring 46 and the angle seat 462 of the right fixed ring 45 to rotate synchronously, so that the stud 465 rotates in the threaded hole, thereby achieving the angle adjustment of the pipe mouth direction, making the pipe mouth direction adjustment more flexible.

[0058] The height of the left fixing ring 46 and the right fixing ring 45 can be adjusted by the height of the fastening of the column by the ring hoop 463. The ring hoop 463 can adopt an open structure, and the opening of the ring hoop 463 is fastened by bolts.

[0059] The movable engaging component 47 includes a movable rod 471 and a engaging plate 472;

[0060] Extension plates are provided on the opening and closing sides of the upper ring 42 and the opening and closing sides of the lower ring 43. Both groups of the extension plates are provided with grooves. A rotatable movable rod 471 is installed in the groove of the extension plate of the upper ring 42. The outer wall of the movable rod 471 is connected with a clamping plate 472 through a plate-like component. After the upper ring 42 and the lower ring 43 are closed, the movable plate rotates so that the plate-like component passes through the extension plate groove of the lower ring 43, and the clamping plate 472 is clamped under the extension plate of the lower ring 43 as the movable plate rotates.

[0061] After the annular component is fixed to the fire pipe mouth, the plate-like component is passed through the extension plate groove of the lower ring 43 by rotating the movable plate, and the clamping plate 472 is clamped under the extension plate of the lower ring 43 as the movable plate rotates, thereby closing the openings of the upper ring 42 and the lower ring 43.

[0062] Another embodiment

[0063] A curved handrail 11 is extended from the top of the upright pole 12 of the left frame 1 and the upright pole 12 of the right frame 2, and the stabilizing column is a rotating type.

[0064] During the fire extinguishing process, it is necessary to move the pipe head according to the fire intensity, and lift the whole device through the handrail 11 so that the diagonal support plate 146 is parallel to the ground, that is, the moving wheel 145 contacts the ground, and the whole device and the pipe head are pushed to move through the handrail 11. During the movement, one foot keeps stepping on the rotating stabilizing column, and the rotating stabilizing column rotates synchronously with the rotation of the moving wheel 145. By stepping on the rotating stabilizing column with one foot, the moving speed of the moving wheel 145 can be controlled, and the impact of the impact force of the high-pressure water flow on the movement of the whole device can be controlled.

[0065] Working principle: The initial state of the device is folded, that is, the left frame 1 and the right frame 2 are folded by the folding component 3, and the annular component is removed. For the convenience of overall carrying, the fixed plug rod 44 on one side of the lower ring 43 can be inserted into the plug hole 461 of any angle seat 462, and the main body of the auxiliary support component 14 is stored in the groove of the counterweight seat 13;

[0066] The firefighter can hold the nozzle of the fire pipe with one hand and carry the folded device with the other hand to move quickly.

[0067] After reaching the predetermined fire position, the auxiliary support rod 143 is unfolded by the unfolding shaft 141, and the reinforcing rod 144 is unfolded by the hinge and nested in the corresponding support hole 142, and the counterweight seat 13 and the auxiliary support rod 143 are unfolded at 60 degrees, and the two groups of fixed plug rods 44 of the lower ring 43 are nested in the corresponding insertion holes 461 of the left fixed ring 46 and the right fixed ring 45, respectively. The annular component is fixed by the two groups of fixed plug rods 44, and the upper ring 42 and the lower ring 43 are opened, and the pipe mouth of the fire hose is inserted between the upper ring 42 and the lower ring 43, and then the upper ring 42 is closed corresponding to the lower ring 43, and the plate-like component is passed through the extension plate groove of the lower ring 43 by rotating the movable plate, and the clamping plate 472 is clamped under the extension plate of the lower ring 43 as the movable plate rotates, thereby closing the opening of the upper ring 42 and the lower ring 43;

[0068] The firefighter steps on the stabilizing rod of the left frame 1 and the stabilizing rod of the right frame 2 with his feet, and holds the handrail 11 on the vertical pole 12 of the left frame 1 and the handrail 11 on the vertical pole 12 of the right frame 2 with his hands, and uses the stability of the 60° triangle and the weight of the firefighter to form gravity pressure on the entire device, and then opens the water valve to make the high-pressure water flow spray out from the nozzle of the fire hose;

[0069] When the angle of the pipe opening needs to be adjusted, the adjustment plate 41 is pushed to make the angle of the annular component rotate around the angle seat 462 as a circle point, and the two groups of fixed insertion rods 44 of the lower ring 43 push the angle seat 462 of the left fixed ring 46 and the angle seat 462 of the right fixed ring 45 to rotate synchronously, so that the stud 465 rotates in the threaded hole, thereby achieving the angle adjustment of the pipe opening direction;

[0070] When the fire situation changes and the pipe mouth needs to be moved, the whole device is lifted up through the handrail 11 so that the diagonal support plate 146 is parallel to the ground, that is, the moving wheel 145 contacts the ground, and the whole device and the pipe head are pushed to move through the handrail 11. During the movement, one foot is kept on the rotating stabilizing column, and the rotating stabilizing column rotates synchronously with the rotation of the moving wheel 145. The moving speed of the moving wheel 145 can be controlled by stepping on the rotating stabilizing column with one foot.
