Abstract

The utility model discloses a shuttle traction trolley which comprises a shuttle trolley, a traction trolley, guide wheels, a trolley rail, two driving gears, a rack and two motors. The shuttle traction trolley is characterized in that the trolley rail is mounted above the shuttle trolley, the two driving gears are respectively mounted on the shuttle trolley, linear reciprocation of the traction trolley on the trolley rail can be realized through transmission of the gears and the rack, synchronous operation control of the traction trolley can be realized by converting rotation movement into linear movement, and the two driving gears are driven by the two independent motors respectively. Stepless regulation of the traction trolley speed within a certain range can be realized, collision of trolleys carrying with green bricks during traction is avoided, and adverse factors of damage of the green bricks caused by the collision are eliminated. Further, rotation speeds of the two gears are kept synchronous, so that mesh precision of the gears and the rack is improved, and the mechanical service life can be prolonged greatly.

Description

A kind of ferry-boat trailer wagon

Technical field

The utility model relates to a kind of ferry-boat trailer wagon, belongs to lifting transportation technology field.

Background technology

The ferry-boat trailer wagon is used widely in infrastructure construction as a kind of transportation means, the constructional drawing of ferry-boat trailer wagon as depicted in figs. 1 and 2 in the prior art, in use there is following defective: when (1) traction is loaded with the dolly of adobe, thereby cause collision between the dolly owing to can not slow down, produce greater impact power, cause adobe to damage; (2) as shown in Figure 1, because two driven wheel rotating speeds are inconsistent, cause the larger error of engagement existence between the rack and pinion, tooth bar can climb to by force at the tooth top of tooth bar under the driving of transmission gear and scoop out on the tooth top of gear, cause the lifting of trailer wagon one end, after the driving gear wheel and rack separates, scoop out gear and become driven wheel continuation driving tooth bar, this moment, rack and pinion meshed together again, one end of trailer wagon lifting drops on the trolley track with larger acceleration due to gravity, will cause in the course of time the major injury of machinery.

The utility model content

Be to solve the deficiencies in the prior art, the utility model provides that a kind of synchronism is good, speed can be regulated, the ferry-boat trailer wagon that the wheel and rack accuracy of mesh is high.

The utility model is achieved by the following technical programs:

A kind of ferry-boat trailer wagon, comprise ferry bus, trailer wagon, track adjusting wheel, trolley track, two driven wheels, tooth bar and two motors, the ferry bus top is equipped with trolley track, track adjusting wheel is installed on the trailer wagon, two driven wheels are installed in respectively on the ferry bus, do the reciprocating linear operation by gear-tooth bar transmission realization trailer wagon at trolley track, be converted to the synchronized operation control that straight-line motion is realized trailer wagon by rotatablely moving.

Described two driven wheels are respectively by two platform independent direct motor drive.

The synchronized operation control of described trailer wagon utilizes the variable frequency control mode to realize operating process.

The beneficial effects of the utility model are:

Convert straight-line motion to owing to will rotatablely move, realize that trailer wagon is to left and right mobile balance, two driven wheels are driven by the electrical motor of two platform independent respectively, utilize the variable frequency control mode to realize operating process, so that mechanical impact force significantly reduces when starting, alleviated the damage of adobe; Trailer wagon speed can be carried out smooth adjustment in certain scope, avoided being loaded with collision between the dolly of adobe in traction, has eliminated the unfavorable factor that therefore causes adobe to damage; The rotating speed of two gears keeps having improved the accuracy of mesh of wheel and rack synchronously, significantly prolonged mechanical service life.

The specific embodiment

Further describe technical scheme of the present invention below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.

With reference to Fig. 3 to Fig. 5, a kind of ferry-boat trailer wagon that the utility model provides, comprise ferry bus 1, trailer wagon 2, track adjusting wheel 3, trolley track 4, two driven wheels 5, tooth bar 7, two motors 8, ferry bus 1 top is equipped with trolley track 4, track adjusting wheel 3 is installed on the trailer wagon 2, two driven wheels 5 are installed in respectively on the ferry bus 1, do the reciprocating linear operation by gear-tooth bar transmission realization trailer wagon 2 at trolley track 4, be converted to the synchronized operation control that straight-line motion is realized trailer wagon 2 by rotatablely moving.

Described two driven wheels 5 are driven by two platform independent electrical motors 8 respectively.

The synchronized operation control of described trailer wagon 2 utilizes the variable frequency control mode to realize operating process.
