[0022] As Figures 1-2In one embodiment shown: a signboard installation device, comprising: a transition connector 4, a turnover mechanism 5, a lead screw structure 6, a clamping assembly 7, a first limiting block 10 and a pressing plate 11, the transition connector 4 comprises: a first telescopic oil cylinder, a basic arm and a plurality of telescopic arms connected thereto, the first telescopic oil cylinder is connected to the basic arm through the plurality of telescopic arms, one side of the first telescopic oil cylinder of the transition connector 4 is connected to the pressing plate 11, one side of the basic arm is connected to the turnover mechanism 5, and the lower end of the turnover mechanism 5 is connected to the lead screw structure 6, which is used to control the angle switching of the lead screw structure 6 and is angle-limited through the first limiting block 10 arranged on the first telescopic oil cylinder, and the lead screw structure 6 is connected to the clamping assembly 7.

[0023] The upper side of the transition connector 4 is connected to the slewing mechanism 2, the upper side of the slewing mechanism 2 is connected to the quick-change connector 1, the hydraulic motor 3 is connected to the slewing mechanism 2, and the hydraulic motor 3 is used to drive the slewing mechanism 2 to control the angle change between the quick-change connector 1 and the transition connector 4.

[0024] The slewing mechanism 2 is provided with an inclination sensor 9 for detecting the angle between the quick-change connector 1 and the transition connector 4.

[0025] The upper side of the transition connector 4 is provided with a second limiting block 12 for limiting the slewing angle of the slewing mechanism 2.

[0026] The pressing plate 11 and the turnover mechanism 5 are arranged on different sides of the transition connector 4, and when the lead screw structure 6 is turned to a horizontal state, the clamping assembly 7 on the lead screw structure 6 is on the same side as the pressing plate 11.

[0027] The turnover mechanism 5 comprises: a second telescopic oil cylinder and an L-shaped piece, the cylinder end of the second telescopic oil cylinder is hinged to the side edge of the basic arm, the rod end of the telescopic oil cylinder is hinged to one end of the L-shaped piece, the other end of the L-shaped piece is hinged to the lower end of the basic arm, the lower side of the L-shaped piece is connected to the lead screw structure 6, and when the rod end of the second telescopic oil cylinder telescopes, the L-shaped piece drives the lead screw structure 6 to rotate by a certain angle.

[0028] The L-shaped piece and the basic arm are hinged through a pin shaft.

[0029] The lead screw structure 6 comprises: a lead screw guide rail, a motor 8 and a sliding block, the sliding block is connected to the lead screw guide rail, one end of the lead screw guide rail is connected to the motor, and two clamping assemblies 7 are connected to the sliding block, which are used to control the relative and separate movements of the clamping assemblies.

[0030] The clamping assembly 7 comprises: an eight-shaped forked clamping body which can gradually lift the signboard 13 from a plane to facilitate clamping the signboard 13, and a nylon plate is arranged on the upper surface of the clamping body to reduce the abrasion with the steel pipe.

[0031] When the clamping body clamps inward, the forks of the two clamping bodies cross each other, and a triangular clamping space is reserved between the clamping bodies.

[0032] like Figure 3 As shown, in this embodiment, the electrical control part is operated by a handle. The handle sends a signal to the body controller, and the CAN signal converter sends a control signal to the pulse transmitter to drive the motor driver. Then the motor is started to run, controlling the movement of the two grippers.

[0033] The hydraulic drive section in this embodiment has two spare hydraulic interfaces, which drive the tilting cylinder and the slewing mechanism respectively, and control the movement of the tilting cylinder and the slewing mechanism.

[0034] like Figures 4-5 As shown, since signs are generally stored horizontally, the gripping assembly is usually kept vertical to grip the signs. The fork-shaped gripping body is kept parallel to the horizontal position. When gripping a single-tube sign, the two gripping assemblies move relative to each other, and the forks gradually lift the single tube from both sides, clamping the single tube through the triangular clamping space formed by the intersecting forks. When gripping a double-tube sign, the two gripping assemblies move apart, and the forks on both sides gradually lift the corresponding single tube, clamping it through the clamping spaces formed by their own forks and the double tubes on both sides of the sign. After the gripping mechanism clamps the sign, it is lifted to a certain height by connecting to the working equipment through the quick-change connector. The flipping cylinder is activated, the second telescopic cylinder extends, and drives the gripping assembly to rotate until the sign is in a vertical position. When the sign moves downward and touches the ground, the sign stops moving downward. At this time, the first telescopic arm continues to compress downward, and the pressure plate touches the top of the sign rod. The pressure plate presses down on the top of the sign rod, realizing the sign insertion operation.

[0035] When removing the sign, the tilting cylinder first keeps the clamping assembly vertical. Then, depending on whether it is a single or double pipe, the clamping assembly is operated to clamp the vertical sign body. The nylon pad of the clamping assembly is controlled to press against the frame below the sign. The sign is then removed by retracting the first telescopic arm. After removal, the tilting cylinder is adjusted to adjust the position of the sign and release the clamping assembly.

[0036] This invention features a high degree of automation, improves work efficiency, and has a wider range of applications, not only suitable for sign installation but also for sign removal.

[0037] This invention utilizes mechanized operations to eliminate the need for manual placement of signs, enabling placement in complex conditions such as mines and swamps.

[0038] The above merely describes the preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present application, and these improvements and modifications should also be considered as the protection scope of the present application.
