Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a tightening device which is easy to move. Background Art

[0002] Inflatable water hoses (such as forest water hoses) play a vital role in forest fire prevention. Their main function is to transport water from the water source to the fire scene to form a water hose to cover the fire area, thereby preventing the spread of fire and achieving the purpose of extinguishing the fire.

[0003] Internal expansion hoses are usually used in conjunction with internal buckle joints (such as forest joints). The interface is connected through an internal expansion hose (hereinafter referred to as the hose) and an internal buckle joint (hereinafter referred to as the joint). A copper sleeve is provided inside the joint. The hose is inserted into the gap between the copper sleeve and the joint, and then the expansion device is inserted into the copper sleeve. The copper sleeve is expanded and deformed by the expansion device so that the joint can be tightly installed on the hose.

[0004] The hose is installed by means of expansion equipment. Traditional expansion equipment is a large volume structure composed of gas tanks and cylinders, and is fixedly installed in the factory for assembly line production. However, in practice, there are often insufficient hoses for fire fighting and damaged hose joints that need to be repaired and replaced. It is necessary to connect the joints to the hoses in real time on site. However, the existing expansion equipment is not easy to carry and transfer to the site, and it is urgent to design a portable expansion equipment to meet the needs of the site. Utility Model Content

[0005] The first aspect of the utility model aims to solve the problem that the existing expansion equipment is inconvenient to carry and transfer to the site, and provides an expansion equipment that is easy to move and use. A moving mechanism can be added to the bottom of the equipment body, and the moving mechanism can facilitate the transportation of the expansion equipment. An auxiliary handle is installed on the expansion equipment to facilitate manual push-pull movement of the expansion equipment. The main concept is:

[0006] A flexible expansion device includes a device body, a moving mechanism and an auxiliary handle. The device body includes a tightening device for tightening a joint. The moving mechanism is installed at the bottom of the device body. The moving mechanism is used to move the device body. The device body is installed with an auxiliary handle. The auxiliary handle is used to provide a force to the device body. In this solution, a moving mechanism is added to the bottom of the device body. The moving mechanism can facilitate the transportation of the expansion device. The auxiliary handle is installed on the expansion device to facilitate manual push-pull movement of the expansion device, thereby facilitating the transfer of the expansion device to the site for use, so that the expansion device can be moved as needed on site.

[0007] Preferably, the moving mechanism includes a plurality of universal casters, which are symmetrically mounted around the device body. The universal casters can rotate freely on a horizontal plane to achieve multi-directional movement, thereby improving the mobility and flexibility of the tensioning device and facilitating pushing, pulling or rotating the tensioning device.

[0008] The second aspect of the utility model aims to solve the problem that the height of the equipment body is too low. If a higher auxiliary handle is fixedly installed, it will be inconvenient to store the equipment body. Furthermore, the auxiliary handle includes a pull rod frame and a sliding guide rail. The sliding guide rail is installed on the equipment body. The sliding guide rail is provided with a groove-shaped channel. The pull rod frame is provided with a guide portion. The guide portion and the groove-shaped channel are slidably matched. The pull rod frame can be pulled out and stored in the equipment body. In this scheme, the sliding guide rail is installed on the equipment body. The guide portion of the pull rod frame is installed in the groove-shaped channel. The guide portion and the groove-shaped channel are slidably matched. By pulling the pull rod frame upward, the pull rod frame can slide along the groove-shaped channel of the sliding guide rail under the action of the guide portion. Not only can the height of the pull rod frame be adjusted at will, but also the pull rod frame can be retracted when the auxiliary handle is not needed, and the pull rod frame can be stored in the equipment body, making the structure of the tensioning device more compact.

[0009] The third aspect of the utility model aims to solve the technical problem that it is difficult to add an auxiliary handle to the side of some equipment bodies. Furthermore, the sliding guide rail is installed on the bottom surface of the equipment body, and the sliding guide rail extends to the outside of the equipment body. The guide part includes a rotating shaft and a pulley. The pull rod frame is connected to the pulley through the rotating shaft, and the pulley is arranged in the groove channel of the sliding guide rail. This scheme installs the auxiliary handle at the bottom of the tensioning device because the length between the working positions of some tensioning devices is too long. If the auxiliary handle is installed on the short side of the equipment body, it will make the pulling balance difficult to grasp. Therefore, this scheme installs the sliding guide rail at the bottom of the equipment body, and installs the pulley at the bottom of the pull rod frame through the rotating shaft. The pulley rolls in the groove channel of the sliding guide rail, so that the pull rod frame can be pulled out from the bottom of the equipment body, and when the pulley of the pull rod frame rolls on the sliding guide rail to the outside of the equipment body, the pull rod frame can realize upward rotation around the rotating shaft.

[0010] Preferably, the sliding guide rail includes a limit end and a rotation end, wherein the limit end is arranged inside the equipment body, and the rotation end is arranged outside the equipment body. The end of the sliding guide rail extending outward is positioned by the hood of the equipment body, and the sliding guide rail is divided into a limit end and a rotation end. When the pulley connected to the pull rod frame by the rotating shaft is located at the limit end inside the equipment body, the pull rod frame is constrained by the baffle of the hood. When the pulley connected to the pull rod frame by the rotating shaft is located at the rotation end outside the hood, the pull rod frame loses the constraint of the baffle of the equipment body, and the pull rod frame rotates upward. The rotation angle of the pull rod frame can be adjusted arbitrarily, and can be adaptively adjusted according to the holding height of the staff when moving the tensioning device. When the tensioning device is pushed and pulled by the pull rod frame, the pull rod frame with an inclined angle can be kept consistent with the inclination angle between the staff's body and arm, reducing the loss of force and saving more effort.

[0011] Preferably, the equipment body also includes a frame, a cover and a power device, the power device is installed on the frame, the cover is arranged outside the frame, the power device includes an output shaft, the power device drives the expansion device through the output shaft, and the expansion device is arranged on the outer side of the equipment body. The installation of the cover can prevent dust from affecting the operation of the expansion device as a whole, and the frame is a supporting frame structure formed by welding multiple steel rectangular tubes, and the power device is installed on the frame by vertically overlapping, so that the overall structure of the expansion device is more compact, and the expansion device is arranged on the outer side of the equipment body to facilitate the expansion processing of the joint.

[0012] Preferably, a cushion is provided at the upper end of the main body of the device, and the cushion is connected to the top of the frame. The overall height of the frame is 400-1000mm, and the operator can touch the ground with both feet when sitting on the cushion to provide balance for the body. A frame is provided inside the expansion device to enhance the strength of the expansion device, and the cushion is installed on the top of the frame, so that when the operator sits on the top of the expansion device through the cushion, the frame can bear the weight of the human body to avoid deformation and damage to the main body of the expansion device. In addition, the cushion is installed on the top of the frame in this solution. When the operator is performing joint expansion work, sitting on the top of the expansion device reduces the height of the operator's operating position, and the center of gravity of the body is transferred to the ischial position through the sitting posture, which will not cause fatigue damage to the knee joints and waist and back.

[0013] The fourth aspect of the utility model aims to solve the technical problem that when the staff is getting on or off the tensioning device, the equipment installed with the moving mechanism will be offset. Furthermore, it also includes a handle, which is installed on the outside of the side of the equipment body. This solution installs the handle on the side of the equipment body, and installs the handle on the outside of the installation surface where the tensioning transposition is not set, which can be convenient for the staff to hold. On the one hand, when the staff sits on or off the cushion on the top of the equipment body, the equipment body can be kept balanced and positioned by holding the handle, so as to avoid the tensioning device from being offset and causing accidents during the process of the staff sitting on or off the cushion; on the other hand, when the tensioning device is transported to a suitable position by pulling the auxiliary handle under the action of the moving mechanism, the staff can accurately adjust the position of the tensioning device through the handle set on the side of the equipment body.

[0014] The beneficial effects of the utility model are:

[0015] By adding a moving mechanism at the bottom of the equipment body, the moving mechanism can facilitate the transportation of the tensioning device, and an auxiliary handle is installed on the tensioning device to facilitate manual pushing and pulling of the tensioning device.

[0024] In order to make the purpose, technical solutions and advantages of the embodiments more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the attached claims.

[0025] It should be noted that all actions to obtain signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located, and with the authorization given by the owner of the corresponding device.

[0026] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", are defined according to the corresponding parts' own contours. The terms used in the present disclosure, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance. Example 1

[0027] like Figure 1-Figure 3 As shown, the present embodiment provides a flexible expansion device which is easy to move, including a device body 1, a movable mechanism 2 and an auxiliary handle 3. The device body 1 includes a tightening device 14 for tightening the joint. The movable mechanism 2 is installed at the bottom of the device body 1, and the movable mechanism 2 is used to move the device body 1. The device body 1 is installed with an auxiliary handle 3, and the auxiliary handle 3 is used to provide a force to the device body 1.

[0028] The moving mechanism 2 of this embodiment includes a plurality of universal casters, which are symmetrically mounted around the device body 1. The universal casters can rotate freely on the horizontal plane to achieve multi-directional movement, improve the mobility and flexibility of the tensioning device, and facilitate the tensioning device to push, pull or rotate.

[0029] like Figure 2As shown, the equipment body 1 includes a frame 11, a cover 12, a power device 13 and a tensioning device 14. The power device 13 is installed on the frame 11, and the cover 12 is arranged outside the frame 11. The power device 13 includes an output shaft, and the power device 13 drives the tensioning device 14 through the output shaft. The tensioning device 14 is arranged on the outer side of the equipment body 1. The installation of the cover 12 can prevent dust from affecting the operation of the tensioning device as a whole. The frame 11 is a supporting frame structure formed by welding a plurality of steel rectangular tubes. The equipment of the power device 13 is installed on the frame 12 in a vertically overlapping manner, so that the overall structure of the tensioning device is more compact. The tensioning device 14 is arranged on the outer side of the equipment body 1 to facilitate the tensioning process of the joint.

[0030] Furthermore, the power device 13 is electrically connected to the power supply assembly, and the power supply assembly supplies power to the power device 13 and other electrical devices. The power supply assembly includes a battery, a power cord, and an aviation plug socket. The battery is installed inside the expansion device so that the power supply assembly can be transported and moved synchronously with the expansion device. During implementation, the power cord is respectively connected to the battery and the aviation plug socket, and the battery is connected to the power device 13 and other electrical devices. The aviation plug socket can be set on the hood 12 of the equipment. When in use, the connecting wire with an aviation plug connector at one end can be connected to the mains and the aviation plug socket respectively, and the connecting wire supplies power to the battery. This connection method can ensure continuous power supply and can also charge the battery. It can play a role when there is no mains interface outdoors or when there is a power outage.

[0031] like Figure 1-Figure 2 As shown, a cushion 8 is provided at the upper end of the device body 1, and the cushion 8 is connected to the top of the frame 11. The overall height of the frame 12 is 400-1000mm, and the operator can touch the ground with both feet when sitting on the cushion 8 to provide balance for the body. The frame 12 is provided inside the expansion device to enhance the strength of the expansion device, and the cushion 8 is installed on the top of the frame 12, so that when the operator sits on the top of the expansion device through the cushion 8, the frame 12 can bear the weight of the human body to avoid deformation and damage to the expansion device body. In addition, the cushion 8 is installed on the top of the frame 12 in this solution. When the operator performs joint expansion work, sitting on the top of the expansion device lowers the height of the operator's operating position, and the center of gravity of the body is transferred to the ischial position through the sitting posture, which will not cause fatigue damage to the knee joint and waist and back.

[0032] like Figure 1 As shown, the auxiliary handle 3 is provided with a handle, which is installed on the top of the side of the device body 1. The handle adopts an arched structure, and the device body 1 is pushed and pulled by holding the handle to achieve the movement of the device body 1 under the action of the moving mechanism 2.

[0033] This equipment is preferably used to connect internal expansion hoses and internal buckle joints, and will not be described in detail below. Example 2

[0034] On the basis of Example 1, Figure 2 As shown, the auxiliary handle 3 of this embodiment includes a pull rod frame 31 and a sliding guide rail 4. The sliding guide rail 4 is installed on the equipment body 1. The sliding guide rail 4 is provided with a groove-shaped channel. The pull rod frame 31 is provided with a guide part. The guide part slides with the groove-shaped channel. The pull rod frame 31 can be pulled out and stored in the equipment body 1.

[0035] The sliding guide rail 4 is installed on the equipment body 1, and the guide part of the pull rod frame 31 is installed in the groove channel. The guide part and the groove channel are slidably matched. By pulling the pull rod frame 31 upward, the pull rod frame 31 can slide along the groove channel of the sliding guide rail 4 under the action of the guide part. Not only can the rising height of the pull rod frame 31 be adjusted at will, but also the pull rod frame 31 can be retracted when the auxiliary handle 3 is not needed, and the pull rod frame 31 can be stored in the equipment body 1, so that the structure of the tensioning device is more compact. Example 3

[0036] like Figure 3 As shown, the equipment body 1 of this embodiment includes a frame 11, a hood 12, a power unit 13 and a tensioning device 14, the power unit 13 is installed on the frame 11, and the hood 12 is arranged outside the frame 11; the power unit 13 of this embodiment includes two output shafts, the two output shafts are respectively arranged on both sides of the power unit 13, and the tensioning device 14 is installed in the output shaft direction on both sides of the power unit 13. In this embodiment, since the length between the working positions of the double-axis tensioning device is too long, if an auxiliary handle is installed on the short side of the equipment body, it will make it difficult to grasp the pulling balance.

[0037] like Figure 4-Figure 7 As shown, on the basis of Example 1, the sliding guide rail 4 is installed on the bottom surface of the equipment body 1, and the sliding guide rail 4 extends to the outside of the equipment body 1. The guide part includes a rotating shaft 5 and a pulley 6. The pull rod frame 31 is connected to the pulley 6 through the rotating shaft 5, and the pulley 6 is arranged in the groove channel of the sliding guide rail 4.

[0038] This solution installs an auxiliary handle at the bottom of the tensioning device because the length between the working positions of some tensioning devices is too long. If the auxiliary handle is installed on the short side of the device body, it will make the pulling balance difficult to grasp. Therefore, this solution installs a sliding guide rail at the bottom of the device body, and installs a pulley at the bottom of the pull rod frame through a rotating shaft. The pulley rolls in the groove channel of the sliding guide rail, so that the pull rod frame can be pulled out from the bottom of the device body, and when the pulley of the pull rod frame rolls on the sliding guide rail to the outside of the device body, the pull rod frame can rotate upward around the rotating shaft.

[0039] like Figure 7 As shown, the sliding guide rail 4 includes a limiting end 41 and a rotating end 42 , wherein the limiting end 41 is arranged inside the device body 1 , and the rotating end 42 is arranged outside the device body 1 .

[0040] The outwardly extending end of the sliding guide rail 4 is positioned through the hood of the equipment body 1, and the sliding guide rail 4 is divided into a limit end 41 and a rotating end 42. When the pulley 6 connected to the pull rod frame 31 through the rotating shaft 5 is located at the limit end 41 inside the equipment body 1, the pull rod frame 31 is constrained by the baffle of the equipment body 1. When the pulley 6 connected to the pull rod frame 31 through the rotating shaft 5 is located at the rotating end outside the equipment body 1, the pull rod frame 31 loses the constraint of the baffle of the equipment body, and the pull rod frame 31 rotates upward, and the rotation angle of the pull rod frame 31 can be adjusted arbitrarily, and can be adaptively adjusted according to the holding height of the staff when moving the tensioning device. When the tensioning device is pushed and pulled by the pull rod frame 31, the pull rod frame 31 maintaining the inclined angle can be consistent with the inclination angle between the staff's body and arm, thereby reducing force loss and saving more effort. Example 4

[0041] like Figure 1-Figure 3 As shown, the tightening device of this embodiment further includes a handle 7 , which is installed on the outside of the side of the device body 1 .

[0042] The handle 7 of the present embodiment is an arched structure, and the handle 7 is installed at the side position of the device body 1. The handle 7 is installed outside the mounting surface of the device body 1 where the tensioning transfer device 14 is not provided, which can be convenient for the staff to hold. On the one hand, when the staff sits on or leaves the seat cushion 8 on the top of the device body 1, the device body 1 can be kept balanced and positioned by holding the handle 7, so as to avoid the tensioning device from shifting and causing accidents when the staff sits on or leaves the seat cushion 8; on the other hand, when the tensioning device is transported to a suitable position by pulling the auxiliary handle 3 under the action of the moving mechanism, the staff can accurately adjust the position of the tensioning device through the handle 7 arranged on the side of the device body.

[0043] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
