Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a track foundation for a bottom mold trolley of a prefabricated beam production line. Background Art

[0002] Existing track foundations usually use cast-in-place concrete. To construct cast-in-place reinforced concrete foundation beams, the site must first be completely cleared, and then the steel bars must be tied, formwork installed, embedded parts installed, and concrete poured. After the construction is completed, the foundation beams are removed. This type of cast-in-place track foundation in temporary construction facilities is prone to material waste and a long construction period. Summary of the invention

[0003] In view of this, the purpose of the utility model is to provide a track foundation for a bottom mold trolley of a precast beam production line to solve the technical problems that cast-in-place track foundations easily cause material waste and a long construction period.

[0004] In order to achieve the above-mentioned purpose, the utility model is a track foundation for a bottom mold trolley of a prefabricated beam production line, and the technical solution adopted is:

[0005] A track foundation for a bottom mold trolley of a prefabricated beam production line, comprising:

[0006] A base, wherein a plurality of the bases are arranged along the construction direction, the bases are spliced ​​and arranged in sequence, and a plurality of first bearing platforms and second bearing platforms arranged in a front-to-back interval are fixed on the base;

[0007] The first supporting platform and the second supporting platform are both provided with a fixed base, and the fixed base is provided with a track, and the track extends in the front-back direction. The first supporting platform and the second supporting platform are used to distribute the weight borne by the track to the base, and fixing parts are provided on both sides of the track, and the fixing parts are used to fix the track on the fixed base.

[0008] The beneficial effect of the above technical solution is that the track foundation of the bottom mold trolley for the precast beam production line of the utility model is spliced ​​and arranged along the construction direction by the base, and can be changed according to specific needs and site conditions. At the same time, an appropriate number of bases are selected according to engineering requirements to adapt to precast beam production lines of different lengths. At the same time, the splicing arrangement provides a certain fault tolerance. If a base is damaged or needs to be replaced during use, only the affected base needs to be replaced without replacing the entire base system, thereby reducing the cost of maintenance and repair. The arrangement of the first pedestal and the second pedestal enables the weight of the track to be evenly distributed to the base. At the same time, fixed bases are arranged on the first pedestal and the second pedestal, and tracks are arranged on the fixed bases, which reduces the load on the first pedestal and the second pedestal. At the same time, the track fasteners and fixing bolts on the fixed base ensure that the track is firmly fixed during use to prevent track loosening caused by operating vibration or other factors, thereby improving the stability and safety of the device.

[0009] Furthermore, the base is provided with a first drainage groove with an opening facing upward, and the first drainage groove extends along the front-to-back direction. The first support platform is arranged at intervals on the left side of the first drainage groove along the front-to-back direction, and the second support platform is arranged at intervals on the right side of the first drainage groove along the front-to-back direction. The first support platform includes a first arc segment, a first straight segment, and a second arc segment connected in sequence from left to right, and the first straight segment is an inclined surface inclined from left to right. The second support platform includes a third arc segment, a second straight segment, and a fourth arc segment connected in sequence from left to right, and the second straight segment is an inclined surface inclined from right to left. The fixed bases on the left and right sides are respectively fixed on the top of the first straight segment and the second straight segment.

[0010] Beneficial effects: The setting of the first drainage ditch helps to effectively drain water and prevent water accumulation. At the same time, the setting of the arc segments of the first pedestal and the second pedestal makes it easier for water to flow to the drainage ditch, reducing the possibility of water accumulation. The inclined setting of the first straight segment and the second straight segment makes the tracks on both sides tilt inward, which can concentrate the wheel-rail contact on the top of the rail and the middle of the wheel tread. The track is subjected to axial force, the lateral bias force is small, and the additional bending stress generated in the rail waist is small, which improves the lateral stability of the track. At the same time, the inclined setting can effectively guide the water flow and reduce the risk of water accumulation.

[0011] Furthermore, the fixing member includes a fastener, which is plate-shaped and has a pressing groove at one end, the bottom of the track is inserted in the pressing groove, the top of the fastener has an adjustment hole that passes through from top to bottom, the fixed base has through holes corresponding to the adjustment hole above and below, the first support platform and the second support platform both have fixing holes corresponding to the through holes, the adjustment hole is penetrated by a fixing bolt, the fixing bolt passes through the adjustment hole, the through hole and the fixing hole in sequence to fix the fastener to the fixed base, and the adjustment hole, the through hole and the fixing hole are all internal threaded holes.

[0012] Beneficial effect: Through the cooperation of fasteners and adjustment holes, the connection between the track and the fixed base is adjustable, so that the track can be fine-tuned as needed to ensure the stability and accuracy of the track. The design of internal threaded holes makes the fixed bolt connection more stable, improving the stability of the entire track foundation.

[0013] Furthermore, a gasket is provided on the top of the fastener, and the gasket is sleeved on the fixing bolt.

[0014] Beneficial effect: The use of gaskets can reduce the looseness of the connection parts.

[0015] Furthermore, a second drainage groove with an upward opening is arranged between the first arc segment and the first straight segment, a third drainage groove with an upward opening is arranged between the second arc segment and the first straight segment, and the bottom of the second drainage groove is higher than the bottom of the third drainage groove, a fourth drainage groove with an upward opening is arranged between the third arc segment and the second straight segment, and a fifth drainage groove with an upward opening is arranged between the fourth arc segment and the first straight segment, and the bottom of the fifth drainage groove is higher than the bottom of the fourth drainage groove.

[0016] Beneficial effect: By setting up the drainage groove, the influence of moisture on the base structure is reduced and the service life of the base is extended. BRIEF DESCRIPTION OF THE DRAWINGS
