In actual installation, the toe guard 2 is vertically installed on the platform assembly 1, and in order to prevent accidents caused by swinging of the toe guard 2 due to lack of fixation during operation of the elevator, the toe guard is fixed by the fixing lugs 3 and the oblique rods 6 which are installed on the platform assembly 1; however, in the prior art, the fixing lugs 3 are usually fixed to the bottom plate or the reinforcing ribs 8 of the platform assembly 1 by welding, and since the fixing lugs 3 are fixed in position and cannot move, the toe guard 2 is prone to dimensional deviation due to mass production, so that the fixing lugs 3 often need to be removed or welded again to ensure accurate field installation, which easily causes cost increase; as for another mounting manner: the fixing lugs 3 are arranged on the reinforcing ribs 8 on the car bottom assembly 1, when the arrangement mode of the reinforcing ribs 8 is vertical to the toe guard 2, the stress requirement of the strength of the car bottom assembly 1 is considered for arrangement of the reinforcing ribs 8, and the reinforcing ribs cannot be unknown according to the position requirement of the fixing lugs 3, so that the situation that one fixing lug 3 is directly welded on the car bottom assembly 1 and the other fixing lug 3 is welded on the reinforcing ribs 8 inevitably occurs, the height difference is caused, and the oblique bars 6 with different lengths are required to be configured.
In order to solve the above problems, in the present application, the support frame 5 is disposed on the car platform assembly 1, specifically, the support frame 5 is mounted on the car platform assembly 1, and the support frame 5 has a C-shaped structure, so that the support frame itself forms a C-shaped groove, the fixing plate 4 and the fixing lugs 3 are clamped by the groove edges 53 of the C-shaped groove one above the other, and then the fixing plate 4 and the fixing lugs 3 are fixed by the bolt assemblies 7, and the groove edges 53 of the C-shaped groove are used as support points, so that the fixing lugs 3 are fixedly mounted, and the fixing lugs 3 can be slidably mounted; specifically, when the position of the fixing lug 3 needs to be adjusted, the fixing lug 3 can be installed in a transposition manner by loosening the bolt assembly 7, sliding the fixing plate 4 and the fixing lug 3 to an installation position along the groove edge 53 of the C-shaped groove, and finally locking the bolt assembly 7, so that the fixing lug 3 does not need to be fixedly installed in a welding manner;
further, when the installation position of the fixing lug 3 changes, the length of the oblique rod 6 also needs to be changed correspondingly, so that the oblique rods 6 with different lengths need to be configured when the installation is carried out on site, which causes an increase in production cost, and in order to avoid the above problems, the fixing lug 3 and the installation plate 21 are provided with the first connection slot 33 and the second connection slot 22; specifically, since the first connecting slot 33 and the second connecting slot 22 have a certain installation length, the inclination angle of the skew bar 6 can be changed by moving the installation positions of the two ends of the skew bar 6 in the first connecting slot 33 and the second connecting slot 22, so as to ensure that the skew bar 6 can meet the installation requirements when the installation position of the fixing lug 3 is changed, and the length of the skew bar 6 does not need to be reconfigured.
Preferably, as shown in fig. 3 to 5, the support frame 5 includes a connecting plate 51 mounted on the platform assembly 1, a riser 52 vertically mounted on both sides of the mounting plate 21 on the same side, and two slot edges 53 inwardly protruding and mounted on the sides of the riser 52;
the two vertical plates 52 are parallel to each other;
the two groove edges 53 are respectively parallel to the connecting plate 51, and an installation notch is formed between the two groove edges 53;
the two sides of the fixing lug 3 and the fixing plate 4 respectively clamp the two groove edges 53, and the bolt assembly 7 is locked from the middle parts of the fixing lug 3 and the fixing plate 4.
Preferably, the fixing lug 3 includes a first lug plate 31 and a second lug plate 32, the first lug plate 31 is fixedly mounted with the fixing plate 4, and the second lug plate 32 is provided with the first connecting slot 33;
the first ear plate 31 is perpendicular to the second ear plate 32.
Preferably, the second ear plate 32 is provided with a first connecting slot hole 33 along the transverse direction;
the mounting plate 21 is provided with the second connecting slot 22 along the vertical direction.
In this embodiment, the connecting plate 51 is attached to the bottom plate of the car platform assembly 1, two vertical plates 52 are vertically fixed to two sides of the connecting plate 51, the two vertical plates 52 are located on the same side and perpendicular to the connecting plate 51, two groove edges 53 are installed on one sides of the two vertical plates 52 far away from the connecting plate 51 and are parallel to the connecting plate 51, and an installation notch is formed between the two groove edges 53, so that the supporting frame 5 is in a C-shaped structure and forms a C-shaped groove, and the installation notch facilitates installation and fixation of the fixing plate 4 and the fixing lugs 3;
as shown in fig. 6, in the first embodiment of the present application:
reinforcing ribs 8 are installed on the car bottom assembly 1, when the reinforcing ribs 8 and the toe guards 2 are vertically installed, the support frame 5 is installed between the reinforcing ribs 8 on two sides, at the moment, the fixing lugs 3 are installed between the reinforcing ribs 8 according to the installation requirement, and the fixing plate 4 and the fixing lugs 3 are fixed through the bolt assemblies 7 only by clamping the groove edges 53 of the C-shaped groove one above the other by the fixing plates 4 and the fixing lugs 3;
as shown in fig. 7, in the second embodiment of the present application:
reinforcing ribs 8 are installed on the car bottom assembly 1, when the reinforcing ribs 8 and the toe guards 2 are vertically installed, the support frame 5 is installed between the reinforcing ribs 8 on the two sides, at the moment, the fixing lugs 3 are installed on the reinforcing ribs 8 according to the installation requirement, namely, the fixing lugs 3 are overlapped with the reinforcing ribs 8, only on the basis of the first embodiment, the bolt assemblies 7 are loosened, then the fixing plates 4 and the fixing lugs 3 slide to the installation positions along the groove edges 53 of the C-shaped grooves, and finally the bolt assemblies 7 are locked, so that the transposition installation of the fixing lugs 3 can be realized; at this time, since the height of the vertical plate 52 of the supporting frame 5 is higher than that of the reinforcing rib 8, the first ear plate 31 of the fixing ear 3 will be attached to the reinforcing rib 8 or have a gap with the reinforcing rib 8, and the installation position of the oblique bar 6 is still on the first connecting slot 33 of the second ear plate 32, and no height difference will be generated between the first ear plate and the other fixing ear 3 installed between the reinforcing ribs 8;
further, when the height of the vertical plate 52 is lower than or equal to the height of the reinforcing rib 8, the second ear plate 32 of the fixing ear 3 fits the reinforcing rib 8, and at this time, because the mounting position of the slant lever 6 is located on the first connecting slot 33 of the second ear plate 32 instead of the first ear plate 31, a height difference between the fixing ear 3 and another fixing ear 3 mounted between the reinforcing ribs 8 still cannot be generated.
Preferably, the support frame 5 is integrally formed.
Preferably, the fixing lug 3 is integrally formed.
The technical principle of the present invention is described above with reference to specific embodiments.
