Description

Telescopic labor-saving mechanism

Technical Field

The utility model relates to the technical field of fire rescue robots, in particular to a telescopic labor-saving mechanism.

Background

With the rapid development of modern economy, the electricity consumption of resident life and industry is continuously increased, and the hidden danger and the probability of fire are greatly increased due to the particularity of modern buildings. In order to deal with the special fire situations, fire rescue robots are developed and widely applied to rescue in emergency situations.

Most of the existing firefighting rescue robots adopt the design of lifting rings so as to be convenient for lifting and carrying of the robots. However, most lifting rings are relatively close to the symmetric center of the rescue robot, and a large force is needed to lift the lifting rings, so that the fire rescue robot is inconvenient to carry and lift.

SUMMERY OF THE UTILITY MODEL

The utility model provides a telescopic labor-saving mechanism, and aims to solve the problems that the existing fire-fighting rescue robot is difficult to carry and pull due to the fact that a lifting ring is closer to a symmetric center of the rescue robot.

The utility model is realized by the following steps:

a retractable, labor-saving mechanism, comprising:

the bottom plate is used for being fixed on the robot;

the supporting frame is arranged on the bottom plate, and a plurality of sliding groove rods are symmetrically arranged on the supporting frame; and

the pull rod is sleeved on the sliding groove rod and can axially move along the sliding groove rod and is fixedly connected with the sliding groove rod through a fixing structure so as to adjust the torque.

Further, in a preferred embodiment of the present invention, the pull rod includes a handle configured to move the pull rod in an axial direction of the chute rod and to lift the robot by the handle after the pull rod and the chute rod are fixed.

Further, in a preferred embodiment of the present invention, the pull rod further includes a plurality of connecting portions adapted to the sliding groove rods, and the connecting portions are respectively sleeved on the corresponding sliding groove rods and slidably connected to the sliding groove rods through a fixing structure.

Further, in a preferred embodiment of the present invention, two sides of the connecting portion are respectively provided with a through hole, and the two through holes are coaxially disposed.

Further, in a preferred embodiment of the present invention, a sliding groove is formed on the sliding groove rod, and the fixing structure sequentially penetrates through the two through holes and the sliding groove to fix the pull rod on the sliding groove rod.

Further, in a preferred embodiment of the present invention, the fixing structure is an adjustable bolt.

The utility model has the beneficial effects that:

the telescopic labor-saving mechanism comprises a bottom plate, a support frame and a pull rod. The supporting frame is arranged on the bottom plate, and a plurality of sliding groove rods are symmetrically arranged on the supporting frame. The pull rod is sleeved on the sliding groove rod and can axially move along the sliding groove rod and is fixedly connected with the sliding groove rod through a fixing structure so as to adjust the torque. The connecting part is sleeved on the sliding groove rod, and the connecting part can move along the axial direction of the sliding groove rod, so that the operability of the labor-saving mechanism can be enhanced, and the labor-saving mechanism is suitable for different conditions. When the adjustable pull rod is used, the pull rod moves towards one end, far away from the support frame, of the sliding groove rod and is fixedly connected with the sliding groove rod through the adjustable bolt, and therefore the purpose of saving labor is achieved by increasing the torque. When the robot is not used, the pull rod can be retracted towards the direction of the support frame so as to reduce occupied space and reserve more space for other operations of the fire rescue robot. In addition, the specific position of the pull rod can be adjusted according to the comfort of the user, so that the pull rod is convenient for the user to carry and lift.

The support frame and the bottom plate are rigidly fixed, so that the firmness of the labor-saving mechanism can be ensured, and the self weight of the fire rescue robot can be borne when the fire rescue robot is lifted.

Referring to fig. 1, an embodiment of the present invention provides a retractable labor-saving mechanism, which includes a bottom plate 1, a supporting frame 2 and a pull rod 3. The base plate 1 is used for being fixed on a robot. The supporting frame 2 is arranged on the bottom plate 1, and a plurality of sliding groove rods 4 are symmetrically arranged on the supporting frame 2. The firmness of the mechanism can be ensured by rigidly fixing the support frame 2 and the bottom plate 1 so as to bear the self weight of the firefighting rescue robot when the firefighting rescue robot is lifted.

The pull rod 3 is sleeved on the sliding groove rod 4 and is constructed to move axially along the sliding groove rod 4 and be fixedly connected with the sliding groove rod 4 through a fixing structure 5 so as to adjust the torque. In this embodiment, two sliding groove rods 4 are symmetrically disposed on two sides of the supporting rod 2, respectively, for adjusting and fixing the position of the pull rod 3. Of course, it should be noted that in other embodiments of the present invention, the number of the chute bars 4 may be set according to needs, and the present invention is not limited in particular.

Referring to fig. 1 and 2, in particular, in the present embodiment, the pull rod 3 includes a handle 31 and a plurality of connecting portions 32 adapted to the chute rod 4. The handle 31 is configured to drive the pull rod 3 to move along the axial direction of the chute rod 4 and lift the robot through the handle 31 after the pull rod 3 and the chute rod 4 are fixed. The connecting portions 32 are respectively sleeved on the corresponding chute rods 4 and are slidably connected with the chute rods 4 through the fixing structures 5. The connecting part 32 is sleeved on the sliding groove rod 4, and the connecting part 32 moves along the axial direction of the sliding groove rod 4, so that the operability of the labor-saving mechanism can be enhanced, and different conditions can be well adapted. When the device is used, the pull rod 3 can be moved to one end far away from the chute rod 4 and locked through the fixing structure 5, so that the aim of saving labor is fulfilled. When not in use, the pull rod 3 can be retracted towards the direction of the support frame 2 to reduce the occupied space, so that more space is reserved for other operations of the fire rescue robot. The specific position of the pull rod 3 can of course also be adjusted to the comfort of the user.

Referring to fig. 1 to 3, in the present embodiment, a through hole 33 is respectively formed on two sides of the connecting portion 32, and the two through holes 33 are coaxially disposed. The chute rod 4 is provided with a chute 41. The fixing structure 5 penetrates the two through holes 33 and the sliding groove 41 in sequence to fix the pull rod 3 on the sliding groove rod 4.

Referring to fig. 1, in the present embodiment, the fixing structure 5 is an adjustable bolt. The user can conveniently adjust the position of the pull rod 3 along the axial direction by loosening the adjustable bolt. After the pull rod 3 is adjusted to a required position, the pull rod 3 and the chute rod 4 can be fixedly connected by screwing the bolt.

The telescopic labor-saving mechanism is simple in structure and convenient to operate, and can effectively control the torque by adjusting the position of the pull rod 3, so that the aim of saving labor is fulfilled. Compared with a lifting ring structure, the labor-saving mechanism can adapt to most scenes, can meet different operation requirements for different working conditions, and can be contracted to reduce occupied space when not used, so that the fire rescue robot is portable. In addition, the rigidity of the pull rod 3 and the chute rod 4 is good, the weight of the fire rescue robot can be borne when the robot is lifted, the robot is not easy to damage, and therefore good integrity is achieved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
