[0006] After adopting the above structure, the control system controls the mobile drive device to control the vehicle body to move forward and backward along the ferry tunnel, and the detection device detects the position of the vehicle body. When the vehicle body is in place, the positioning device limits the position of the vehicle body, thereby realizing the automatic forward and backward movement and transportation of the prefabricated beam bottom mold trolley and reaching different placement points. The transportation rhythm is stable, which improves the connection and coordination between different workstations and production lines, and greatly improves production efficiency.

[0007] Preferably, the bottom of the vehicle body is uniformly provided with a plurality of active wheel sets and passive wheel sets for supporting the vehicle body to walk; the active wheel set comprises an active wheel frame fixed on the bottom of the vehicle body and an active wheel rotatably installed on the active wheel frame; the mobile driving device is drivingly connected with the active wheel; the active wheel rolls in the front-rear direction along the transfer tunnel, and the rolling direction is perpendicular to the extension direction of the transverse track; the passive wheel set comprises a passive wheel frame fixed on the bottom of the vehicle body and a passive wheel rotatably installed on the passive wheel frame; the passive wheel rolls in the front-rear direction along the transfer tunnel, and the rolling direction is the same as that of the active wheel. Through this arrangement, sliding friction is changed to rolling friction, and the friction is reduced, thereby ensuring the stable and reliable operation of the vehicle body.

[0008] Preferably, the mobile driving device is drivingly connected with the active wheel. Through this arrangement, the connection between the vehicle body and the transfer tunnel is limited, thereby simplifying the mobile driving device and facilitating maintenance and replacement.

[0009] Preferably, the transfer tunnel is provided with longitudinal tracks for limiting the rolling of the active wheel and the passive wheel; the longitudinal tracks extend in the front-rear direction along the transfer tunnel. Through this arrangement, the movement track of the vehicle body is limited, thereby avoiding the left-right shaking of the vehicle body and affecting the subsequent transfer.

A detection post is provided on the positioning block, switching between the two positioning sensors. When the detection post is in the locking position, the positioning block inserts into the limiting slot, locking the vehicle position. When the detection post is in the unlocking position, the positioning block moves out of the limiting slot, unlocking the vehicle position. This arrangement allows for precise monitoring of the positioning device's status, facilitating automated control.

DETAILED DESCRIPTION

[0026] The present application is further described below with reference to the drawings.

[0027] The directions referred to in the specification are based on the normal working position of the prefabricated beam heavy-load transfer device, and are not limited to the storage and transportation positions, and only represent relative positional relationships, not absolute positional relationships.

[0028] As shown in Figure 1 , a prefabricated beam heavy-load transfer device includes a vehicle body 1 that is movably installed in a transfer tunnel, a moving drive device 2 that drives the vehicle body 1 to move, a detection device that detects the position of the vehicle body 1, a positioning device that limits the forward and backward movement of the vehicle body 1, and a control system.

[0029] The vehicle body 1 is a frame structure extending left and right, and a plurality of transverse tracks 11 extending left and right are fixedly installed on the upper surface of the vehicle body 1, and a prefabricated beam bottom die trolley (not shown in the figure) slides left and right along the transverse tracks 11; in this embodiment, in order to ensure that the prefabricated beam bottom die trolley can slide stably, the transverse tracks 11 are provided in two.

[0030] The vehicle body 1 can be installed in the transfer tunnel in a sliding or rolling manner, and in order to reduce friction, the rolling manner is adopted in this embodiment.

[0031] The specific installation manner is as shown in Figure 2 and Figure 3 , a plurality of driving wheel sets 21 and driven wheel sets 22 for supporting the vehicle body 1 to move are uniformly installed on the bottom of the vehicle body 1; the driving wheel set 21 includes a driving wheel frame 211 fixed to the bottom of the vehicle body 1 and a driving wheel 212 rotatably installed on the driving wheel frame 211; the driving wheel 212 rolls in the forward and backward directions along the transfer tunnel, and the rolling direction is perpendicular to the extension direction of the transverse track 11; the moving drive device 2 is transmissionally connected to the driving wheel 212, and the moving drive device 2 can adopt a chain or traction rope structure to drive the vehicle body 1 to move forward and backward along the transfer tunnel; in order to reduce the dependence of the vehicle body 1 on the transfer tunnel and simplify the installation process, the moving drive device 2 is an electric motor and a speed reducer fixed to the driving wheel frame 211 in this embodiment; the output shaft of the speed reducer is transmissionally connected to the wheel shaft of the driving wheel 212, and the driving wheel 212 is driven to rotate by the moving drive device 2. The motor is signal-connected to the control system.

[0032] The driven wheel assembly 22 includes a driven wheel frame 221 fixed to the bottom of the vehicle body 1 and a driven wheel 222 rotatably mounted on the driven wheel frame 221 ; the driven wheel 222 rolls forward and backward along the ferry tunnel, and its rolling direction is the same as that of the driving wheel 212 .

[0033] As an improvement to the above embodiment, the vehicle body 1 can be an integrated structure. In this embodiment, in order to facilitate the assembly of the vehicle body 1, the vehicle body 1 is composed of multiple sets of frames that can be detachably spliced ​​together on the left and right sides. In this embodiment, there are three sets. In actual application, they can be assembled according to the left and right lengths of the prefabricated beam bottom mold trolley, such as two or four sets. The bottom of each set of frames includes at least two sets of driving wheel sets 21 and at least two sets of driven wheel sets 22; in this embodiment, the bottom of each set of frames includes two sets of driving wheel sets 21 and six sets of driven wheel sets 22; the two sets of driving wheel sets 21 are fixed front and back to the left side of the bottom of the frame, while the six sets of driven wheel sets 22 are fixed front and back relatively evenly to the right side of the bottom of the frame. By providing multiple sets of driving wheel sets 21 and driven wheel sets 22, stable support for the vehicle body 1 is guaranteed and the force on a single support point is reduced.

[0034] In order to ensure the position accuracy of the vehicle body 1 moving forward and backward, a longitudinal track is provided in the ferry tunnel for the driving wheel 212 and the driven wheel 222 to limit the rolling. The longitudinal track extends forward and backward along the ferry tunnel.

[0035] like Figure 1 and Figure 5 As shown, the detection device includes a sensing device 31 mounted on the vehicle body 1 and a trigger device installed at different locations within the ferry tunnel. The sensing device 31 can be a position sensor or a photoelectric sensor, and the trigger device is a sensor plate fixed to the bottom of the ferry tunnel. In this embodiment, three sensing devices 31 are arranged side by side, each corresponding to a different sensor plate. When a corresponding sensing device 31 senses the corresponding sensor plate, the vehicle body 1 is in place. The sensing device signals are connected to the control system.

[0036] like Figure 1 and Figure 4 As shown, the positioning device includes a positioning base 41 fixed to the bottom of the vehicle body 1, a positioning block 42 movably mounted on the bottom of the positioning base 41, and a positioning drive 43 that drives the positioning block 42 into or out of the positioning hole in the ferry tunnel. The positioning drive 43 is connected to the control system. The positioning block 42 is mounted on the positioning base 41 in a sliding manner. The positioning drive 43 drives the positioning block 42 to slide up and down into the positioning hole, thereby limiting the position of the vehicle body 1.

[0037] like Figure 6 and Figure 7As another embodiment of the positioning device, the positioning block 42 is a cam block structure, in this embodiment, a sector block, which is rotatably mounted on the positioning base 41; the rotation direction is the left-right direction; and the positioning driving device 43 is fixed on the positioning base 41 and drives the positioning block 42 to rotate. The positioning hole includes two positioning columns 44 fixed on the bottom of the transfer tunnel in front and back directions, and the distance between the two positioning columns 44 forms a limiting slot; when the positioning block 42 rotates, it can be inserted or removed from one side of the limiting slot. The vehicle body 1 is uniformly provided with a plurality of positioning devices in the left-right direction; because the left-right length of the vehicle body 1 is relatively long, in order to avoid its left-right direction deviation, the plurality of positioning devices ensure the stability of the parallelism of the vehicle body 1 in the left-right direction.

[0038] When the detection device has a detection error, the front and back positions of the positioning block 42 will have a slight deviation; at this time, when the positioning block 42 rotates, the positioning block 42 will collide with one of the positioning columns 44; in order to ensure that the positioning block 42 can be smoothly inserted into the limiting slot, the left side of the positioning block 42 in this embodiment is provided with a guide slope 421 at the collision position of the front and back ends and the corresponding side of the positioning column 44; when the positioning block 42 collides with the positioning column 44, the positioning column 44 abuts against the guide slope 421, and as the positioning block 42 continues to rotate, the vehicle body 1 will be adjusted forward and backward under the action of the guide slope 421, so that it can be smoothly inserted into the limiting slot.

[0039] As an improvement of the above embodiment, in order to avoid hard friction between the positioning column 44 and the guide slope 421, a bearing is rotatably mounted on the positioning column 44, and the bearing is in contact with the guide slope 421.

[0040] As an improvement of the above embodiment, in order to accurately determine the position of the positioning block 42 and facilitate automatic operation, two positioning sensors 411 are mounted on the positioning base 41, and the two positioning sensors 411 correspond to the locking position and the unlocking position of the positioning block 42, respectively; a detection column 422 is arranged on the positioning block 42 and is converted between the two positioning sensors 411; when the detection column 422 is located at the locking position, the positioning block 42 is inserted into the limiting slot, and the position of the vehicle body 1 is locked; when the detection column 422 is located at the unlocking position, the positioning block 42 is removed from the limiting slot, and the position of the vehicle body 1 is unlocked.

[0041] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples; changes, modifications, additions or replacements made by those skilled in the art within the scope of the present application should also be within the protection scope of the present application.
