[0019] The utility model provides a kind of fire-fighting lance support of convenient adjustment as shown in Figs. 1 to 4 The support column 1 is vertically arranged as a square column, and a rectangular mounting groove is formed in the support column 1.

[0020] A sliding rod 2 is vertically arranged in the mounting groove, and the sliding rod 2 passes out of the support column 1 upward and is limited to slide with the support column 1.

[0021] The driving member includes a second electric push rod 9. A horizontal support plate 10 is arranged in the mounting groove, and the support plate 10 is fixedly connected with the support column 1. The second electric push rod 9 is fixedly installed at the top of the support plate 10, the telescopic shaft of the second electric push rod 9 is vertically upward and is fixedly connected with a transmission block 8, and the transmission block 8 is fixedly connected with the sliding rod 2.

[0022] A horizontal sliding plate 11 is installed in the mounting groove, and the sliding plate 11 is a square plate and is limited to slide with the support column 1. The sliding plate 11 is located below the sliding rod 2, and the support plate 10 is located above the sliding plate 11. A through hole is formed in the middle position of the support plate 10, the sliding rod 2 passes through the through hole and abuts against the sliding plate 11 to drive the sliding plate 11 to slide downward.

[0023] A reset member is installed in the mounting groove, and the reset member is drivingly connected with the sliding plate 11 to drive the sliding plate 11 to slide upward.

[0024] The reset member includes four springs 13, and the four springs 13 are distributed in a matrix around the center of gravity of the sliding plate 11. All the springs 13 are located between the support plate 10 and the sliding plate 11, one end of each spring 13 is fixedly connected with the support plate 10, and the other end of each spring 13 is fixedly connected with the sliding plate 11.

[0025] Four universal wheels 12 are assembled at the bottom of the sliding plate 11, and the four universal wheels 12 correspond to the four springs 13 one by one. Each universal wheel 12 passes out of the bottom opening of the mounting groove downward.

[0026] A connecting ball 7 is fixedly arranged at the top of the sliding rod 2, the connecting ball 7 is hingedly fixed to a fixed seat 3, a clamping mechanism is installed on the fixed seat 3, and the clamping mechanism clamps the fire-fighting lance.

[0027] The clamping mechanism includes a first electric push rod 4, and the first electric push rod 4 is fixedly installed on the fixed seat 3. A clamping hole is formed in the fixed seat 3, the clamping hole is a through hole, and the fire-fighting lance penetrates through the clamping hole. The clamping hole is a polygonal hole formed by a rectangular hole located above and a triangular hole located below.

[0028] The rectangular hole is internally limited to slide with a rectangular clamping block 5, the bottom of the clamping block 5 is provided with an inverted V-shaped clamping groove, the groove inner wall of the clamping groove and the hole inner wall of the triangular hole jointly form a rhombus clamping structure to clamp the fire water gun. The telescopic shaft of the first electric push rod 4 penetrates into the clamping hole and is fixedly connected with the clamping block 5.

[0029] A horizontal handle 6 is fixedly arranged on the fixed seat 3. The number of the handle 6 is two and the fixed seat 3 is located between the two handles 6. It is convenient for the firefighter to hold.

[0030] Working principle: when in use, the firefighter inserts the fire water gun into the clamping hole, then starts the first electric push rod 4, the telescopic shaft of the first electric push rod 4 extends and pushes the clamping block 5 to move towards the fire water gun. When the clamping block 5 contacts and abuts against the fire water gun, the first electric push rod 4 is turned off.

[0031] When it is needed to adjust the height of the fire water gun, the second electric push rod 9 is started, the telescopic shaft of the second electric push rod 9 extends and pushes the transmission block 8 to move upwards. At this time, the transmission block 8 drives the sliding rod 2 to slide upwards, the sliding rod 2 drives the connecting ball 7 to move upwards. The connecting ball 7 drives the fixed seat 3 to move upwards, the fixed seat 3 drives the fire water gun to move upwards.

[0032] When it is needed to move the support, the second electric push rod 9 is started again, the telescopic shaft of the second electric push rod 9 retracts and drives the sliding rod 2 to slide downwards through the transmission block 8. The bottom end of the sliding rod 2 penetrates downwards through the through hole on the support plate 10 and gradually contacts the sliding plate 11. When the bottom end of the sliding rod 2 contacts the sliding plate 11, the sliding plate 11 is pushed to slide relative to the support column 1 towards the opening at the bottom of the mounting groove.

[0033] In this process, all the universal wheels 12 slide through the opening at the bottom of the mounting groove relative to the support column 1. At the same time, all the springs 13 are stretched.

[0034] After that, all the universal wheels 12 abut against the ground, the support column 1 is jacked up. When the universal wheels 12 completely penetrate out of the support column 1, the second electric push rod 9 is turned off, at this time, the sliding plate 11 is still located in the mounting groove. Then the support column 1 can be pushed to move.

[0035] When it is needed to stabilize the support column 1, the second electric push rod 9 is started again, the telescopic shaft of the second electric push rod 9 extends and pushes the sliding rod 2 to slide upwards through the transmission block 8. In the process of the sliding rod 2 sliding upwards, all the springs 13 contract, at this time, under the action of the gravity and the elastic force of all the springs 13, the sliding plate 11 slides upwards relative to the support column 1, the support column 1 moves downwards relative to the ground until contacting the ground.

[0036] After that, when the sliding rod 2 is completely separated from the sliding plate 11, the second electric push rod 9 can be turned off.

[0037] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
