Summary of the invention

The present invention overcomes the deficiency that prior art exists, and technical matters to be solved is to provide a kind of turntable be connected with car body for arm, drives arm to rotate to certain position, reduces operation easier, ensure that job security when car body is motionless.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: the arm turntable on transport trolley, comprise base, support for rotary disc, top rotary table, intermediate active frame, HM Hydraulic Motor and gear ring, support for rotary disc is mounted by means of bolts on base, top rotary table be the disk like of back-off and movable button on support for rotary disc, the horizontal contact face of top rotary table and support for rotary disc is provided with the groove that matches and lays multiple first steel ball in groove, be installed with intermediate active frame in the middle of the bottom surface of top rotary table and intermediate active chord position in support for rotary disc, the circumference side of described top rotary table is installed with gear ring, HM Hydraulic Motor is fixedly mounted on support for rotary disc side by motor bracket and the output shaft of HM Hydraulic Motor is installed with the gear be meshed with gear ring,

Arm journal stirrup is installed with above described top rotary table.

The bottom inside face of described support for rotary disc and the bottom outside face of intermediate active frame are equipped with corresponding groove, and in two grooves, a coupling link is installed, in the groove that the side of described coupling link is mounted by means of bolts on intermediate active frame and opposite side active card is contained in the groove of support for rotary disc, coupling link upper surface and the contact surface of support for rotary disc are provided with the groove that matches and lay multiple second steel ball in groove.

Between described support for rotary disc and intermediate active frame, multiple roller is installed.

Described HM Hydraulic Motor is coated with motor shroud.

The excircle side of described top rotary table is coated with gear ring guard shield on earth between seat, and gear ring is the inside with gear ring guard shield.

The beneficial effect that the present invention is compared with the existing technology had is: support for rotary disc supports rotatable top rotary table, HM Hydraulic Motor drives top rotary table to rotate by the cooperation of gear and gear ring, realize the multi-directional rotation of arm, inner intermediate active frame is that support for rotary disc reduces abutment pressure, avoids it to bear a heavy burden reduction of service life comparatively greatly; Coupling link between support for rotary disc and intermediate active frame ensure that and both relative distance prevents it to be subjected to displacement; First steel ball, the second steel ball and roller are the friction force in order to reduce contact surface, make it relatively rotate lighter; In order to protect HM Hydraulic Motor and gear ring when motor shroud and gear ring guard shield, prevent falling object in tunnel or water to the infringement of HM Hydraulic Motor and gear ring.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the invention will be further described.

Fig. 1 is structural representation of the present invention.

In figure: 1 is base, 2 is support for rotary disc, and 3 is top rotary table, and 4 is intermediate active frame, and 5 is coupling link, 6 is HM Hydraulic Motor, and 7 is gear ring, and 8 is the first steel ball, and 9 is motor bracket, and 10 is gear, 11 is arm journal stirrup, and 12 is motor shroud, and 13 is gear ring guard shield, and 14 is the second steel ball, and 15 is roller.

Detailed description of the invention

As shown in Figure 1, arm turntable on transport trolley of the present invention, comprise base 1, support for rotary disc 2, top rotary table 3, intermediate active frame 4, HM Hydraulic Motor 6 and gear ring 7, support for rotary disc 2 is mounted by means of bolts on base 1, top rotary table 3 be the disk like of back-off and movable button on support for rotary disc 2, the horizontal contact face of top rotary table 3 and support for rotary disc 2 is provided with the groove that matches and lays multiple first steel ball 8 in groove, the centre, bottom surface of top rotary table 3 is installed with intermediate active frame 4 and intermediate active frame 4 is positioned at support for rotary disc 2, the circumference side of described top rotary table 3 is installed with gear ring 7, HM Hydraulic Motor 6 is fixedly mounted on support for rotary disc 2 side by motor bracket 9 and the output shaft of HM Hydraulic Motor 6 is installed with the gear 10 be meshed with gear ring 7,
