Description

Technical Field

[0001] The present invention belongs to the technical field of conveying equipment, and in particular relates to a high-low track cross-conversion device and method. Background Art

[0002] The segmental beams of the east-west approach bridges of the Huangmaohai Cross-sea Channel are 2,270 pieces. A segmental beam prefabrication yard is built on a soft foundation, with 4 production lines and 16 prefabricated tires, 8 longitudinal beam shifting tracks and 8 gantry crane tracks, 16 transverse beam shifting tracks, and 64 cross-intersection positions. The track specification of the beam shifting trolley is 70 heavy-duty rails, and the 200-ton prefabricated beams are moved on the track by the beam shifting trolley. The track specification of the gantry crane is 43 rails, and a 20-meter-high gantry crane hoists a 20-ton steel cage and moves on the track. There is a 2cm height difference between the 70 heavy-duty rail and the 43 rail, and the longitudinal and transverse track conversion is relatively frequent. The installation of a high and low cross-track conversion device has become an important factor affecting the safety and progress of the segmental beam prefabrication construction.

[0003] Patent CN106743473A discloses a switching device for cross-track docking, including a track arm, a track arm support mechanism that can drive the track arm to rotate, the track arm support mechanism is connected to a traction mechanism, the track arm support mechanism includes an axle seat, an axle disc that can rotate on the axle seat, the track arm is fixed to the upper end face of the axle disc, the lower end face of the axle disc is connected to one end of the bending arm, and the other end of the bending arm is connected to the traction mechanism. The present invention has the following advantages: the device can change the direction of movement at the intersection of the track through the rotation function of the mechanism, and the device can be transferred from the working position to the storage position; the cylinder telescopically drives the track to reciprocate, and the positioning of the limit block ensures that the rotating track is accurately docked with the two cross-tracks.

[0004] However, this technical solution has at least the following problems: In this type of solution, the track arm is driven to rotate by the track arm support mechanism in the above patent, so that the track is converted after the position of the track arm is adjusted. The structure is relatively complex, and the track arm support mechanism occupies a large space. In addition, during the rotation process, since the end of the corresponding track needs to be docked with the track arm, a gap is easily generated between the track arm and the corresponding track, resulting in poor connection accuracy. At the same time, since there is no support on both sides of the track arm, it is also easy to cause the track arm to swing during driving, resulting in safety accidents. Summary of the invention

[0020] Example 1 The present invention provides a high-low track cross conversion device, comprising a cross steel plate base 1, track one 7 and track two, wherein track one 7 and track two are matched with two vertical direction structures of the cross steel plate base 1 respectively. The high-low track cross-conversion device provided by the present invention can quickly realize the conversion of the cross track through the cooperation of the cross steel plate base 1 and the track 1 7 and the track 2. It solves the problem that the bolts 6 are often disassembled when the track is fixed by bolts 6 and pressure plates in the past, and the bolts 6 become loose, which poses a great safety risk. It also greatly improves the efficiency of the cross track conversion, reduces the input of personnel, and reduces the safety risk.

[0021] Example 2 Based on Example 1, this embodiment provides a high-low track cross-conversion device, such as Figure 1 As shown, the cross steel plate base 1 includes a steel plate bottom plate 2 and a cross side plate, the cross side plate is arranged on the bottom plate, the cross side plate includes a side plate 1 3 and a side plate 2 4, the side plate 1 3 and the side plate 2 4 are four pieces and are vertically arranged, two parallel side plates 1 3 form a group, two parallel side plates 2 4 form a group, one end of the two side plates 1 3 in a group are respectively connected to the two groups of side plates 2 4 to form a hollow cross.

[0022] According to different specifications of tracks in the longitudinal and transverse directions, the side plate 1 3 and the side plate 2 4 are different in height. The side plate 1 3 and the side plate 2 4 are both steel plates.

[0023] Example 3 On the basis of Example 1, this example provides a high-low track cross-conversion device, in which a steel plate support 5 is provided between adjacent side panels 1 3 and 2 4 .

[0024] like Figure 1 and Figure 2 As shown, two adjacent side panels 1 3 and 2 4 that are perpendicular to each other are connected by a steel plate support 5 to increase the stability of the structure.

[0025] Example 4 Based on Example 1, this example provides a high-low track cross conversion device, wherein the cross side plate is connected to the track joint 8 of the high-low track, and the top of the cross side plate is flush with the lower edge of the flange 9 of the track joint 8.

[0026] like Figure 3 As shown, the top of the cross side plate is flush with the lower edge of the flange 9 of the track joint 8, ensuring that when the track is switched, the track 1 7, the track 2 and the high and low tracks are flush, thereby allowing smooth vehicle passing.

[0027] Example 5 On the basis of Example 1, this example provides a high-low track cross-conversion device, and the flatness of the steel plate bottom plate 2 is controlled within 2 mm.

[0028] The thickness of the webs [FX2][3]10 of track 1 7 and track 2 is less than 2 mm of the width of the cross side plate.

[0029] By controlling the flatness of the steel plate bottom plate 2, the smooth passage of the trolley after the track conversion is further ensured, so as to prevent the steel plate bottom plate from being deformed and the track from being broken during the running of the trolley.

[0030] The thickness of the web 10 of Track 1 7 and Track 2 is less than 2 mm of the width of the cross side plate. On the one hand, it is convenient for Track 1 7 and Track 2 to be inserted into the cross side plate. On the other hand, the fit between the web 10 and the cross side plate provides left and right support force to prevent Track 1 7 and Track 2 from tilting after being compressed.

[0031] Example 6 Based on Example 1, this example provides a high and low track cross conversion device, wherein the webs 10 of Track 1 7 and Track 2 are inserted into the cross side plates, and the wing plates of Track 1 7 and Track 2 are flush with the track surfaces of the high and low tracks.

[0032] The cross side plate and the track joint 8 of the high and low tracks are connected by bolts 6. The side view of the high and low tracks is as follows: Figure 4 As shown, the cross side plate is inserted into both sides of the web plate 10 of the high and low tracks, and then the cross side plate and the track joint 8 of the high and low tracks are connected by bolts 6. When the tracks are switched, there is no need to loosen the bolts 6, and only the track 1 7 and the track 2 need to be replaced and inserted into the corresponding positions, which has high conversion efficiency.

[0033] The track 1 7 and track 2 are both T-shaped. Figure 5 and Figure 6 The cross-sections of track 1 7 and track 2 are T-shaped, which facilitates the insertion of track 1 7 between the two side plates 1 3 , and similarly, facilitates the insertion of track 2 between the two side plates 2 4 .

[0034] This embodiment takes the use of the segmental beam prefabrication yard as an example. It is necessary to use a beam shifting trolley and a gantry crane. The gantry crane track specification is 43 rails. A 20-meter-high gantry crane hoists a 20-ton steel cage on the track ( Figure 2 The beam-shifting trolley is a 70 heavy-duty rail. The 200-ton prefabricated beam is moved on the track ( Figure 2 Walking on the middle track 1-7).

[0035] There is a 2cm height difference between the 70 heavy rail and the 43 rail, and the high-low rail cross-conversion device of the present invention is installed at the cross-intersection. When the beam-shifting trolley moves horizontally, the heavy 70 "T" type rail is installed in advance into the steel plate notch (formed by a set of side plates 3). After the beam-shifting trolley passes, when the gantry crane needs to pass longitudinally, the heavy 70 "T" type rail is taken out and the 43 "T" type rail is installed, thereby achieving the effect of cross-track cross-conversion.

[0036] Example 7 On the basis of Example 1, this embodiment provides a high-low track cross conversion method, using a high-low track cross conversion device, including the following steps: Step 1) Cut off a section of the cross intersection of the high track and the low track symmetrically along the center to form a rectangular gap, wherein the cut length of the high track and the low track is equal to the length of track 17 and track 2 respectively; Step 2) Place the cross steel plate base 1 at the rectangular notch, insert the track joints 8 of the high and low tracks into the cross side plate, and then use bolts 6 to fix the cross side plate and the four track joints 8; Step 3) insert the web 10 of track 1 7 into the two sets of side plates 1 3 to achieve walking in the direction of the track; Step 4) When there is a need to pass in the other track direction, pull out the track 1 7, insert the web 10 of the track 2 into the two sets of side plates 2 4, and realize the cross-track cross-conversion.

[0037] In summary, the cross-conversion device of the high and low tracks of the present invention successfully solves the problem that the bolts 6 are often disassembled when the track is fixed by bolts 6 and pressure plates in the past, and the bolts 6 become loose, which poses a great safety risk. It also greatly improves the efficiency of cross-track conversion, reduces personnel input, and reduces safety risks. It has great use prospects and reference value in subsequent large beam yards and factory construction.
